Что такое инструменты анализа в excel

Анализ данных в Excel предполагает сама конструкция табличного процессора. Очень многие средства программы подходят для реализации этой задачи.

Excel позиционирует себя как лучший универсальный программный продукт в мире по обработке аналитической информации. От маленького предприятия до крупных корпораций, руководители тратят значительную часть своего рабочего времени для анализа жизнедеятельности их бизнеса. Рассмотрим основные аналитические инструменты в Excel и примеры применения их в практике.

Инструменты анализа Excel

Одним из самых привлекательных анализов данных является «Что-если». Он находится: «Данные»-«Работа с данными»-«Что-если».

Средства анализа «Что-если»:

1. «Подбор параметра». Применяется, когда пользователю известен результат формулы, но неизвестны входные данные для этого результата.
2. «Таблица данных». Используется в ситуациях, когда нужно показать в виде таблицы влияние переменных значений на формулы.
3. «Диспетчер сценариев». Применяется для формирования, изменения и сохранения разных наборов входных данных и итогов вычислений по группе формул.
4. «Поиск решения». Это надстройка программы Excel. Помогает найти наилучшее решение определенной задачи.

Практический пример использования «Что-если» для поиска оптимальных скидок по таблице данных.

Другие инструменты для анализа данных:

Анализировать данные в Excel можно с помощью встроенных функций (математических, финансовых, логических, статистических и т.д.).



Сводные таблицы в анализе данных

Чтобы упростить просмотр, обработку и обобщение данных, в Excel применяются сводные таблицы.

Программа будет воспринимать введенную/вводимую информацию как таблицу, а не простой набор данных, если списки со значениями отформатировать соответствующим образом:

1. Перейти на вкладку «Вставка» и щелкнуть по кнопке «Таблица».
2. Откроется диалоговое окно «Создание таблицы».



3. Указать диапазон данных (если они уже внесены) или предполагаемый диапазон (в какие ячейки будет помещена таблица). Установить флажок напротив «Таблица с заголовками». Нажать Enter.

К указанному диапазону применится заданный по умолчанию стиль форматирования. Станет активным инструмент «Работа с таблицами» (вкладка «Конструктор»).

Составить отчет можно с помощью «Сводной таблицы».

1. Активизируем любую из ячеек диапазона данных. Щелкаем кнопку «Сводная таблица» («Вставка» — «Таблицы» — «Сводная таблица»).
2. В диалоговом окне прописываем диапазон и место, куда поместить сводный отчет (новый лист).
3. Открывается «Мастер сводных таблиц». Левая часть листа – изображение отчета, правая часть – инструменты создания сводного отчета.



4. Выбираем необходимые поля из списка. Определяемся со значениями для названий строк и столбцов. В левой части листа будет «строиться» отчет.

Создание сводной таблицы – это уже способ анализа данных. Более того, пользователь выбирает нужную ему в конкретный момент информацию для отображения. Он может в дальнейшем применять другие инструменты.

Анализ «Что-если» в Excel: «Таблица данных»

Мощное средство анализа данных. Рассмотрим организацию информации с помощью инструмента «Что-если» — «Таблица данных».

Важные условия:

• данные должны находиться в одном столбце или одной строке;
• формула ссылается на одну входную ячейку.

Процедура создания «Таблицы данных»:

1. Заносим входные значения в столбец, а формулу – в соседний столбец на одну строку выше.



2. Выделяем диапазон значений, включающий столбец с входными данными и формулой. Переходим на вкладку «Данные». Открываем инструмент «Что-если». Щелкаем кнопку «Таблица данных».



3. В открывшемся диалоговом окне есть два поля. Так как мы создаем таблицу с одним входом, то вводим адрес только в поле «Подставлять значения по строкам в». Если входные значения располагаются в строках (а не в столбцах), то адрес будем вписывать в поле «Подставлять значения по столбцам в» и нажимаем ОК.

Анализ предприятия в Excel: примеры

Для анализа деятельности предприятия берутся данные из бухгалтерского баланса, отчета о прибылях и убытках. Каждый пользователь создает свою форму, в которой отражаются особенности фирмы, важная для принятия решений информация.

• скачать систему анализа предприятий;
• скачать аналитическую таблицу финансов;
• таблица рентабельности бизнеса;
• отчет по движению денежных средств;
• пример балльного метода в финансово-экономической аналитике.

Для примера предлагаем скачать финансовый анализ предприятий в таблицах и графиках составленные профессиональными специалистами в области финансово-экономической аналитике. Здесь используются формы бухгалтерской отчетности, формулы и таблицы для расчета и анализа платежеспособности, финансового состояния, рентабельности, деловой активности и т.д.

Суть и методы анализа данных

Американский учёный-статистик Джон Тьюки в 1961 году сформулировал определение анализа данных. Под ним он подразумевал как сами процедуры анализа, так и методы интерпретации результатов этих процедур, а также способы планирования сбора данных в целях упрощения и уточнения анализа и результаты математической статистики, используемые для анализа.

В связи с этим анализ данных представляет собой деятельность по извлечению крупных неструктурированных данных из самых разных источников, а также их реорганизацию в информацию, которая может быть использована в целях:

• ответа на вопросы;
• проверки гипотез;
• принятия решений;
• опровержения теорий.

Есть несколько способов анализа данных, которые распространяются на многочисленные области, от маркетинга до науки. Можно выделить несколько базовых вариантов:

Сбор данных

Data Mining – это анализ больших информационных объемов в целях получения прежде неоткрытых, полезных моделей данных, нестандартных данных, а также выявления зависимостей. Стоит упомянуть, что в качестве главной задачи выступает извлечение не самих данных, а шаблонов и знаний из больших информационных объемов.

Анализ данных производится на основе различных методов информатики, в том числе систем искусственного интеллекта, машинного обучения, статистики и баз данных.

Шаблоны, которые извлекаются посредством интеллектуального анализа данных, могут определяться как сводка входных данных. Они в свою очередь могут быть применены в последующем анализе либо для извлечения более детализированных результатов прогнозирования системой поддержки принятия решений.

Бизнес-аналитика

Суть бизнес-аналитики заключается в сборе и трансформации больших объемов неструктурированных бизнес-данных, что, в свою очередь, необходимо для упрощения определения, разработки и формирования новых стратегических бизнес-возможностей.

Иными словами, главная задача бизнес-аналитики — сделать процесс интерпретации больших объемов данных более простым, чтобы выявлять новые возможности. Все это способствует разработке результативной стратегии, базирующейся на концепциях, которые могут сформировать конкурентное преимущество на рынке и стабилизировать компанию в долгосрочной перспективе.

Статистический анализ

Статистику можно определить как изучение произведенного сбора, анализа, интерпретации, представления и организации данных.

В процессе анализа данных применяют 2 базовых метода статистики:

• Описательная статистика

Данная разновидность статистики предполагает суммирование данных от всей совокупности или выборки посредством числовых дескрипторов. В качестве этих дескрипторов выступают:

• среднее значение, стандартное отклонение для непрерывных данных;
• частота, процент для категориальных данных.

• Статистическая статистика

В этом случае применяются образцы в выборочных данных в целях формирования выводов о представленной совокупности или учета случайности. Выделяют следующие разновидности выводов:

• ответы на вопросы да / нет о данных (проверка гипотез);
• оценка числовых характеристик данных (оценка);
• описание связей в данных (корреляция);
• моделирование отношений в данных (к примеру, регрессионный анализ).

Прогнозная аналитика

Predictive Analytics применяет статистические модели в целях анализа нынешних и исторических данных. Это необходимо для создания прогнозов относительно дальнейших или иных неизвестных событий. В предпринимательстве эта разновидность анализа применяется в целях определения рисков и возможностей, способствующих принятию правильных решений. 

Текстовая аналитика

Text Analytics (Text Mining, Text Data Mining) — это процесс извлечения из текста информации высокого уровня качества. Можно выделить несколько составляющих анализа текста:

• процесс структурирования исходного текста;
• извлечение шаблонов из структурированных данных с применением метода изучения статистических шаблонов и др.;
• оценка и интерпретация полученной информации.

С помощью Microsoft Excel можно использовать целый ряд средств и методов для анализа и интерпретации данных. При этом данные могут быть получены из разных источников. Имеется несколько вариантов трансформации и форматирования данных. Анализ можно осуществлять посредством различных команд, функций и инструментов программы.

В частности, к ним можно отнести условное форматирование, диапазоны, таблицы, текстовые функции, функции даты, функции времени, финансовые функции, промежуточные итоги, быстрый анализ, аудит формул, инструмент Inquire, анализ «что, если», решатели, модель данных, PowerPivot, PowerView, PowerMap и многое другое.

Активация и запуск функций анализа данных в Excel

Excel представляет собой не только редактор таблиц, а еще и отличный инструмент, позволяющий производить всевозможные математические и статистические расчеты. Программа отличается широким функционалом, позволяющим осуществлять вышеописанные процедуры. Однако некоторые из этих функций неактивны по умолчанию. Анализ данных в Excel является как раз такой скрытой возможностью.

Если вы хотите активировать данную функцию, то следует зайти в настройки Microsoft Excel. Причем для разных версий утилиты (2010, 2013 и 2016 года) последовательность действий будет примерно одна и та же. Несущественные расхождения в алгоритме действий имеются лишь для версии 2007 года.

Итак, необходимо выполнить следующие действия:

1. Нажать на вкладку «Файл» (либо на логотип Microsoft Office в верхнем левом углу экрана для версии 2007 года).
2. Нажать на один из пунктов в левой части открывшегося окна — «Параметры».
3. Перейти в подраздел «Надстройки» (второй с конца в списке в левой части окна).
4. Здесь нужно обратить внимание на нижнюю часть окна. Следует найти параметр «Управление». Обратите внимание на значение в выпадающей форме — вы должны увидеть «Надстройки Excel». Далее следует нажать на вкладку «Перейти…» справа от этого пункта. Если же в выпадающей форме вы увидите какое-то другое значение, нужно будет сначала вписать то, которое мы указали выше.
5. В открывшемся окне доступных надстроек найдите пункт «Пакет анализа» и поставьте возле него галочку. Затем нажмите на кнопку «OK» (в правой верхней части).

Выполнив все перечисленные действия, вы активируете нужную функцию и получите соответствующие инструменты. Найти их можно в ленте Excel.

Чтобы открыть тот или иной инструмент анализа данных, нужно произвести следующие действия:

1. Зайти в раздел «Данные».
2. Найти блок инструментов «Анализ», который расположен на правом краю ленты и нажать на «Анализ данных».
3. Выбрать конкретный инструмент из появившегося списка. Наиболее полезными считаются:

• корреляция;
• гистограмма;
• регрессия;
• выборка;
• экспоненциальное сглаживание;
• генератор случайных чисел;
• описательная статистика;
• анализ Фурье;
• различные виды дисперсионного анализа и т.д.

Выбрав нужный инструмент, нажмите на кнопку «OK». Каждый из доступных инструментов работает на основе своего собственного алгоритма.

Таким образом, блок функций «Пакет анализа» включается с помощью всего лишь нескольких простых шагов. При этом если не знать четкую последовательность действий, пользователю сложно найти нужную кнопку.

4 техники анализа данных в Excel

Сводные таблицы

Это важнейший инструмент для обработки больших информационных объемов. Сводные таблицы позволяют быстро делать выводы на основе неструктурированных данных без ручной сортировки и фильтрации. Создание и настройка таблиц осуществляется довольно быстро. Однако от того, какой именно вариант отображения результата вам нужен, будет зависеть алгоритм настройки.

Кроме того, у пользователя есть возможность создавать сводные диаграммы на базе сводных таблиц. При изменении таблиц диаграммы будут обновляться в автоматическом режиме. Скажем, если вы на регулярной основе формируете отчёты по одним и тем же параметрам, то такая функция вам очень пригодится.

Можно вписать какие угодно исходные параметры, например, данные по продажам, отгрузкам, доставкам и т.д.

Для использования сводной таблицы вам необходимо:

• Открыть файл с таблицей, данные которой необходимо проанализировать.
• Выделить диапазон данных для анализа.
• Перейти на вкладку «Вставка», а затем «Таблица». Далее нужно нажать на «Сводная таблица» (для macOS на вкладке «Данные» в группе «Анализ»). Если вы сделали все правильно, то появится диалоговое окно «Создание сводной таблицы».
• Настроить отображение данных, которые есть у вас в таблице.

3D-карты

Благодаря этому методу визуализации данных с географической привязкой вы сможете проанализировать данные и выявить закономерности, имеющие региональное происхождение.

Однако вам не нужно указывать координаты, ведь если правильно ввести географическое название в таблице, программа сделает все сама.

Для применения инструмента вас нужно:

• Открыть файл с таблицей, информацию из которой необходимо визуализировать. К примеру, с данными по разным городам и странам.
• Подготовить данные для отображения на карте. Для этого нужно нажать на «Главная» и перейти на вкладку «Форматировать как таблицу».
• Обозначить диапазон данных для анализа.
• На вкладке «Вставка» вы увидите кнопку «3D-карта».

На карте имеются точки, обозначающие города. Однако нам нужно увидеть информацию, которая привязана к этим городам, например, суммы, отображающиеся через высоту столбика. Если навести курсор на столбик, то вы увидите сумму.

Вместе с тем, довольно полезной считается круговая диаграмма по годам, в которой размер круга зависит от суммы.

Лист прогнозов

В бизнес-процессах имеют место сезонные закономерности. Их, конечно же, нужно учитывать во время планирования. Для этой цели лучше всего подходит «Лист прогноза», который является самым точным инструментом для осуществления прогнозов в рамках Excel. Его применяют для планирования деятельности коммерческих, финансовых, маркетинговых и прочих служб.

Чтобы сделать прогноз, необходимо иметь информацию за предыдущие периоды. Чем больше информации будет внесено, тем более точный прогноз вы получите (минимальный объём информации для хорошего прогноза — 1 год). Учтите, что нужны одинаковые интервалы между точками данных (скажем, месяц или равное количество дней).

Чтобы использовать данную функцию, вам необходимо:

• Открыть таблицу с данными за период и соответствующими ему параметрами, к примеру, от года.
• Выделить 2 ряда данных.
• На вкладке «Данные» нажать на кнопку «Лист прогноза».
• В окне «Создание листа прогноза» выбрать подходящий график или гистограмму для визуализации прогноза.
• Определить дату окончания прогноза.

Быстрый анализ

Данный инструмент позволяет выполнять процедуры анализа в кратчайшие сроки. Чтобы получить необходимые данные, достаточно нажать всего на несколько кнопок. Вам не нужно будет производить никаких расчетов или указывать какие-либо формулы. Единственное что от вас потребуется — выделить нужный диапазон и выбрать тип результата, который вам необходим на выходе.

Благодаря данному инструменту вы можете формировать всевозможные разновидности диаграмм или спарклайны (микрографики прямо в ячейке) буквально в два счета.

Чтобы работать с инструментом, вам нужно:

• Открыть таблицу с данными для анализа.
• Выделить необходимый для анализа диапазон.
• Во время выделения диапазона в нижней части высвечивается кнопка «Быстрый анализ».

Нажав на эту кнопку, вы сможете произвести целый ряд различных действий, которые предложит программа. К примеру, найти итоги. Кроме того, можно узнать суммы, которые проставляются внизу.

Быстрый анализ предполагает несколько способов форматирования. Чтобы узнать, какие значения больше, а какие меньше, нужно перейти в ячейки гистограммы.

Плюс ко всему, вы можете выставить в ячейках значки разных цветов: зелёные — самые большие значения, красные — самые меньшие.

Все эти инструменты позволят вам ускорить процесс анализа данных и сделать его более простым. Используя различные функции, вы сможете с легкостью освоить Microsoft Excel и извлечь из него максимальную пользу.

Data Analysis — Overview

Data Analysis is a process of inspecting, cleaning, transforming and modeling data with the goal of discovering useful information, suggesting conclusions and supporting decision-making

.

Types of Data Analysis

Several data analysis techniques exist encompassing various domains such as business, science, social science, etc. with a variety of names. The major data analysis approaches are −

• Data Mining
• Business Intelligence
• Statistical Analysis
• Predictive Analytics
• Text Analytics

Data Mining

Data Mining is the analysis of large quantities of data to extract previously unknown, interesting patterns of data, unusual data and the dependencies. Note that the goal is the extraction of patterns and knowledge from large amounts of data and not the extraction of data itself.

Data mining analysis involves computer science methods at the intersection of the artificial intelligence, machine learning, statistics, and database systems.

The patterns obtained from data mining can be considered as a summary of the input data that can be used in further analysis or to obtain more accurate prediction results by a decision support system.

Business Intelligence

Business Intelligence techniques and tools are for acquisition and transformation of large amounts of unstructured business data to help identify, develop and create new strategic business opportunities.

The goal of business intelligence is to allow easy interpretation of large volumes of data to identify new opportunities. It helps in implementing an effective strategy based on insights that can provide businesses with a competitive market-advantage and long-term stability.

Statistical Analysis

Statistics is the study of collection, analysis, interpretation, presentation, and organization of data.

In data analysis, two main statistical methodologies are used −

• Descriptive statistics − In descriptive statistics, data from the entire population or a sample is summarized with numerical descriptors such as −

  • Mean, Standard Deviation for Continuous Data

  • Frequency, Percentage for Categorical Data

• Inferential statistics − It uses patterns in the sample data to draw inferences about the represented population or accounting for randomness. These inferences can be −

  • answering yes/no questions about the data (hypothesis testing)

  • estimating numerical characteristics of the data (estimation)

  • describing associations within the data (correlation)

  • modeling relationships within the data (E.g. regression analysis)

Predictive Analytics

Predictive Analytics use statistical models to analyze current and historical data for forecasting (predictions) about future or otherwise unknown events. In business, predictive analytics is used to identify risks and opportunities that aid in decision-making.

Text Analytics

Text Analytics, also referred to as Text Mining or as Text Data Mining is the process of deriving high-quality information from text. Text mining usually involves the process of structuring the input text, deriving patterns within the structured data using means such as statistical pattern learning, and finally evaluation and interpretation of the output.

Data Analysis Process

Data Analysis is defined by the statistician John Tukey in 1961 as «Procedures for analyzing data, techniques for interpreting the results of such procedures, ways of planning the gathering of data to make its analysis easier, more precise or more accurate, and all the machinery and results of (mathematical) statistics which apply to analyzing data.”

Thus, data analysis is a process for obtaining large, unstructured data from various sources and converting it into information that is useful for −

• Answering questions
• Test hypotheses
• Decision-making
• Disproving theories

Data Analysis with Excel

Microsoft Excel provides several means and ways to analyze and interpret data. The data can be from various sources. The data can be converted and formatted in several ways. It can be analyzed with the relevant Excel commands, functions and tools — encompassing Conditional Formatting, Ranges, Tables, Text functions, Date functions, Time functions, Financial functions, Subtotals, Quick Analysis, Formula Auditing, Inquire Tool, What-if Analysis, Solvers, Data Model, PowerPivot, PowerView, PowerMap, etc.

You will be learning these data analysis techniques with Excel as part of two parts −

• Data Analysis with Excel and
• Advanced Data Analysis with Excel

Data Analysis — Process

Data Analysis is a process of collecting, transforming, cleaning, and modeling data with the goal of discovering the required information. The results so obtained are communicated, suggesting conclusions, and supporting decision-making. Data visualization is at times used to portray the data for the ease of discovering the useful patterns in the data. The terms Data Modeling and Data Analysis mean the same.

Data Analysis Process consists of the following phases that are iterative in nature −

• Data Requirements Specification
• Data Collection
• Data Processing
• Data Cleaning
• Data Analysis
• Communication

Data Requirements Specification

The data required for analysis is based on a question or an experiment. Based on the requirements of those directing the analysis, the data necessary as inputs to the analysis is identified (e.g., Population of people). Specific variables regarding a population (e.g., Age and Income) may be specified and obtained. Data may be numerical or categorical.

Data Collection

Data Collection is the process of gathering information on targeted variables identified as data requirements. The emphasis is on ensuring accurate and honest collection of data. Data Collection ensures that data gathered is accurate such that the related decisions are valid. Data Collection provides both a baseline to measure and a target to improve.

Data is collected from various sources ranging from organizational databases to the information in web pages. The data thus obtained, may not be structured and may contain irrelevant information. Hence, the collected data is required to be subjected to Data Processing and Data Cleaning.

Data Processing

The data that is collected must be processed or organized for analysis. This includes structuring the data as required for the relevant Analysis Tools. For example, the data might have to be placed into rows and columns in a table within a Spreadsheet or Statistical Application. A Data Model might have to be created.

Data Cleaning

The processed and organized data may be incomplete, contain duplicates, or contain errors. Data Cleaning is the process of preventing and correcting these errors. There are several types of Data Cleaning that depend on the type of data. For example, while cleaning the financial data, certain totals might be compared against reliable published numbers or defined thresholds. Likewise, quantitative data methods can be used for outlier detection that would be subsequently excluded in analysis.

Data Analysis

Data that is processed, organized and cleaned would be ready for the analysis. Various data analysis techniques are available to understand, interpret, and derive conclusions based on the requirements. Data Visualization may also be used to examine the data in graphical format, to obtain additional insight regarding the messages within the data.

Statistical Data Models such as Correlation, Regression Analysis can be used to identify the relations among the data variables. These models that are descriptive of the data are helpful in simplifying analysis and communicate results.

The process might require additional Data Cleaning or additional Data Collection, and hence these activities are iterative in nature.

Communication

The results of the data analysis are to be reported in a format as required by the users to support their decisions and further action. The feedback from the users might result in additional analysis.

The data analysts can choose data visualization techniques, such as tables and charts, which help in communicating the message clearly and efficiently to the users. The analysis tools provide facility to highlight the required information with color codes and formatting in tables and charts.

Excel Data Analysis — Overview

Excel provide commands, functions and tools that make your data analysis tasks easy. You can avoid many time consuming and/or complex calculations using Excel. In this tutorial, you will get a head start on how you can perform data analysis with Excel. You will understand with relevant examples, step by step usage of Excel commands and screen shots at every step.

Ranges and Tables

The data that you have can be in a range or in a table. Certain operations on data can be performed whether the data is in a range or in a table.

However, there are certain operations that are more effective when data is in tables rather than in ranges. There are also operations that are exclusively for tables.

You will understand the ways of analyzing data in ranges and tables as well. You will understand how to name ranges, use the names and manage the names. The same would apply for names in the tables.

Data Cleaning – Text Functions, Dates and Times

You need to clean the data obtained from various sources and structure it before proceeding to data analysis. You will learn how you can clean the data.

• With Text Functions
• Containing Date Values
• Containing Time Values

Conditional Formatting

Excel provides you conditional formatting commands that allow you to color the cells or font, have symbols next to values in the cells based on predefined criteria. This helps one in visualizing the prominent values. You will understand the various commands for conditionally formatting the cells.

Sorting and Filtering

During the preparation of data analysis and/or to display certain important data, you might have to sort and/or filter your data. You can do the same with the easy to use sorting and filtering options that you have in Excel.

Subtotals with Ranges

As you are aware, PivotTable is normally used to summarize data. However, Subtotals with Ranges is another feature provided by Excel that will allow you to group / ungroup data and summarize the data present in ranges with easy steps.

Quick Analysis

With Quick Analysis tool in Excel, you can quickly perform various data analysis tasks and make quick visualizations of the results.

Understanding Lookup Functions

Excel Lookup Functions enable you to find the data values that match a defined criteria from a huge amount of data.

PivotTables

With PivotTables you can summarize the data, prepare reports dynamically by changing the contents of the PivotTable.

Data Visualization

You will learn several Data Visualization techniques using Excel Charts. You will also learn how to create Band Chart, Thermometer Chart, Gantt chart, Waterfall Chart, Sparklines and PivotCharts.

Data Validation

It might be required that only valid values be entered into certain cells. Otherwise, they may lead to incorrect calculations. With data validation commands, you can easily set up data validation values for a cell, an input message prompting the user on what is expected to be entered in the cell, validate the values entered with the defined criteria and display an error message in case of incorrect entries.

Financial Analysis

Excel provides you several financial functions. However, for commonly occurring problems that require financial analysis, you can learn how to use a combination of these functions.

Working with Multiple Worksheets

You might have to perform several identical calculations in more than one worksheet. Instead of repeating these calculations in each worksheet, you can do it one worksheet and have it appear in the other selected worksheets as well. You can also summarize the data from the various worksheets into a report worksheet.

Formula Auditing

When you use formulas, you might want to check whether the formulas are working as expected. In Excel, Formula Auditing commands help you in tracing the precedent and dependent values and error checking.

Inquire

Excel also provides Inquire add-in that enables you compare two workbooks to identify changes, create interactive reports, and view the relationships among workbooks, worksheets, and cells. You can also clean the excessive formatting in a worksheet that makes Excel slow or makes the file size huge.

Working with Range Names

While doing Data Analysis, referring to various data will be more meaningful and easy if the reference is by Names rather than cell references – either a single cell or a range of cells. For example, if you are calculating Net Present Value based on a Discount Rate and a series of Cash Flows, the formula

Net_Present_Value = NPV (Discount_Rate, Cash_Flows)

is more meaningful than

C10 = NPV (C2, C6:C8)

With Excel, you can create and use meaningful names to various parts of your data. The advantages of using range names include −

• A meaningful Range name (such as Cash_Flows) is much easier to remember than a Range address (such as C6:C8).

• Entering a name is less error prone than entering a cell or range address.

• If you type a name incorrectly in a formula, Excel will display a #NAME? error.

• You can quickly move to areas of your worksheet by using the defined names.

• With Names, your formulas will be more understandable and easier to use. For example, a formula Net_Income = Gross_Income – Deductions is more intuitive than C40 = C20 – B18.

• Creating formulas with range names is easier than with cell or range addresses. You can copy a cell or range name into a formula by using formula Autocomplete.

In this chapter, you will learn −

• Syntax rules for names.
• Creating names for cell references.
• Creating names for constants.
• Managing the names.
• Scope of your defined names.
• Editing names.
• Filtering names.
• Deleting names.
• Applying names.
• Using names in a formula.
• Viewing names in a workbook.
• Using paste names and paste list.
• Using names for range intersections.
• Copying formulas with names.

Copying Name using Formula Autocomplete

Type the first letter of the name in the formula. A drop-down box appears with function names and range names. Select the required name. It is copied into your formula.

Range Name Syntax Rules

Excel has the following syntax rules for names −

• You can use any combination of letters, numbers and the symbols — underscores, backslashes, and periods. Other symbols are not allowed.

• A name can begin with a character, underscore or backslash.

• A name cannot begin with a number (example — 1stQuarter) or resemble a cell address (example — QTR1).

• If you prefer to use such names, precede the name with an underscore or a backslash (example — 1stQuarter, _QTR1).

• Names cannot contain spaces. If you want to distinguish two words in a name, you can use underscore (example- Cash_Flows instead of Cash Flows)

• Your defined names should not clash with Excel’s internally defined names, such as Print_Area, Print_Titles, Consolidate_Area, and Sheet_Title. If you define the same names, they will override the Excel’s internal names and you will not get any error message. However, it is advised not to do so.

• Keep the names short but understandable, though you can use up to 255 characters

Creating Range Names

You can create Range Names in two ways −

• Using the Name box.

• Using the New Name dialog box.

• Using the Selection dialog box.

Create a Range Name using the Name Box

To create a Range name, using the Name box that is to the left of formula bar is the fastest way. Follow the steps given below −

Step 1 − Select the range for which you want to define a Name.

Step 2 − Click on the Name box.

Step 3 − Type the name and press Enter to create the Name.

Create a Range Name using the New Name dialog box

You can also create Range Names using the New Name dialog box from Formulas tab.

Step 1 − Select the range for which you want to define a name.

Step 2 − Click the Formulas tab.

Step 3 − Click Define Name in the Defined Names group. The New Name dialog box appears.

Step 4 − Type the name in the box next to Name

Step 5 − Check that the range that is selected and displayed in the Refers box is correct. Click OK.

Create a Range Name using the Create Names from Selection dialog box

You can also create Range names using the Create Names from the Selection dialog box from Formulas tab, when you have Text values that are adjacent to your range.

Step 1 − Select the range for which you want to define a name along with the row / column that contains the name.

Step 2 − Click the Formulas tab.

Step 3 − Click Create from Selection in the Defined Names group. The Create Names from Selection dialog box appears.

Step 4 − Select top row as the Text appears in the top row of the selection.

Step 5 − Check the range that got selected and displayed in the box next to Refers to be correct. Click OK.

Now, you can find the largest value in the range with =Sum(Student Name), as shown below −

You can create names with multiple selection also. In the example given below, you can name the row of marks of each student with the student’s name.

Now, you can find the total marks for each student with =Sum (student name), as shown
below.

Creating Names for Constants

Suppose you have a constant that will be used throughout your workbook. You can assign a name to it directly, without placing it in a cell.

In the example below, Savings Bank Interest Rate is set to 5%.

• Click Define Name.
• In the New Name dialog box, type Savings_Bank_Interest_Rate in the Name box.
• In Scope, select Workbook.
• In Refers to box, clear the contents and type 5%.
• Click OK.

The Name Savings_Bank_Interest_Rate is set to a constant 5%. You can verify this in Name Manager. You can see that the value is set to 0.05 and in the Refers to =0.05 is placed.

Managing Names

An Excel Workbook can have any number of named cells and ranges. You can manage these names with the Name Manager.

• Click the Formulas tab.

• Click Name Manager in the Defined Names group. The Name Manager dialog box appears. All the names defined in the current workbook are displayed.

The List of Names are displayed with the defined Values, Cell Reference (including Sheet Name), Scope and Comment.

The Name Manager has the options to −

• Define a New Name with the New Button.

• Edit a Defined Name.

• Delete a Defined Name.

• Filter the Defined Names by Category.

• Modify the Range of a Defined Name that it Refers to.

Scope of a Name

The Scope of a name by default is the workbook. You can find the Scope of a defined names from the list of names under the Scope column in the Name Manager.

You can define the Scope of a New Name when you define the name using New Name dialog box. For example, you are defining the name Interest_Rate. Then you can see that the Scope of the New Name Interest_Rate is the Workbook.

Suppose you want the Scope of this interest rate restricted to this Worksheet only.

Step 1 − Click the down-arrow in the Scope Box. The available Scope options appear in the drop-down list.

The Scope options include Workbook, and the sheet names in the workbook.

Step 2 − Click the current worksheet name, in this case NPV and click OK. You can define / find the sheet name in the worksheet tab.

Step 3 − To verify that Scope is worksheet, click Name Manager. In the Scope column, you will find NPV for Interest_Rate. This means you can use the Name Interest_Rate only in the
Worksheet NPV, but not in the other Worksheets.

Note − Once you define the Scope of a Name, it cannot be modified later.

Deleting Names with Error Values

Sometimes, it may so happen that Name definition may have errors for various reasons. You can delete such names as follows −

Step 1 − Click Filter in the Name Manager dialog box.

The following filtering options appear −

• Clear Filter
• Names Scoped to Worksheet
• Names Scoped to Workbook
• Names with Errors
• Names without Errors
• Defined Names
• Table Names

You can apply Filter to the defined Names by selecting one or more of these options.

Step 2 − Select Names with Errors. Names that contain error values will be displayed.

Step 3 − From the obtained list of Names, select the ones you want to delete and click Delete.

You will get a message, confirming delete. Click OK.

Editing Names

You can use the Edit option in the Name Manager dialog box to −

• Change the Name.

• Modify the Refers to range

• Edit the Comment in a Name.

Change the Name

Step 1 − Click the cell containing the function Large.

You can see, two more values are added in the array, but are not included in the function as they are not part of Array1.

Step 2 − Click the Name you want to edit in the Name Manager dialog box. In this case, Array1.

Step 3 − Click Edit. The Edit Name dialog box appears.

Step 4 − Change the Name by typing the new name that you want in the Name Box.

Step 5 − Click the Range button to the right of Refers to Box and include the new cell references.

Step 6 − Add a Comment (Optional)

Notice that Scope is deactive and hence cannot be changed.

Click OK. You will observe the changes made.

Applying Names

Consider the following example −

As you observe, names are not defined and used in PMT function. If you place this function somewhere else in the worksheet, you also need to remember where exactly the parameter values are. You know that using names is a better option.

In this case, the function is already defined with cell references that do not have names. You can still define names and apply them.

Step 1 − Using Create from Selection, define the names.

Step 2 − Select the cell containing the formula. Click next to Define Name in the Defined Names group on the Formulas tab. From the drop-down list, click Apply Names.

Step 3 − The Apply Names dialog box appears. Select the Names that you want to Apply and click OK.

The selected names will be applied to the selected cells.

You can also Apply Names to an entire worksheet, by selecting the worksheet and repeating the above steps.

Using Names in a Formula

You can use a Name in a Formula in the following ways −

• Typing the Name if you remember it, or

• Typing first one or two letters and using the Excel Formula Autocomplete feature.

• Clicking Use in Formula in the Defined Names group on the Formulas tab.

  • Select the required Name from the drop-down list of defined names.

  • Double-click on that name.

• Using the Paste Name dialog box.

  • Select the Paste Names option from the drop-down list of defined names. The
    Paste Name dialog box appears.

  • Select the Name in the Paste Names dialog box and double-click it.

Viewing Names in a Workbook

You can get all the Names in your workbook along with their References and Save them or Print them.

• Click an empty Cell where you want to copy the Names in your workbook.

• Click Use in Formula in the Defined Names group.

• Click Paste Names from the drop-down list.

• Click Paste List in the Paste Name dialog box that appears.

The list of names and their corresponding references are copied at the specified location on your worksheet as shown in the screen shot given below −

Using Names for Range Intersections

Range Intersections are those individual cells that have two Ranges in common.

For example, in the data given below, the Range B6:F6 and the Range C3:C8 have Cell C6 in common, which actually represents the marks scored by the student Kodeda, Adam in Exam 1.

You can make this more meaningful with the Range Names.

• Create Names with Create from Selection for both Students and Exams.

• Your Names will look as follows −

• Type =Kodeda_Adam Exam_1 in B11.

Here, you are using the Range Intersection operation, space between the two ranges.

This will display marks of Kodeda, Adam in Exam 1, that are given in Cell C6.

Copying Formulas with Names

You can copy a formula with names by Copyand Paste within the same worksheet.

You can also copy a formula with names to a different worksheet by copy and paste, provided all the names in the formula have workbook as Scope. Otherwise, you will get a #VALUE error.

Excel Data Analysis — Tables

A Table is a rectangular range of structured data. The key features are −

• Each row in the table corresponds to a single record of the data. Example — Employee information.

• Each column contains a specific piece of information. Exmaple — The columns can contain data such as name, employee number, hire date, salary, department, etc.

• The top row describes the information contained in each column and is referred to as header row.

• Each entry in the top row is referred to as column header.

You can create and use an Excel table to manage and analyze data easily. Further, with Excel Tables you get built-in Filtering, Sorting, and Row Shading that ease your reporting activities.

Further, Excel responds to the actions performed on a table intelligently. For example, you have a formula in a column or you have created a chart based on the data in the table. When you add more data to the table (i.e., more rows), Excel extends the formula to the new data and the chart expands automatically.

Difference between Tables and Ranges

Following are the differences between a table and range −

• A table is a more structured way of working with data than a range.
• You can convert a range into a table and Excel automatically provides −
  • a Table Name
  • Column Header Names
  • Formatting to the Data (Cell Color and Font Color) for better Visualization

Tables provide additional features that are not available for ranges. These are −

• Excel provides table tools in the ribbon ranging from properties to styles.

• Excel automatically provides a Filter button in each column header to sort the data or filter the table such that only rows that meet your defined criteria are displayed.

• If you have multiple rows in a table, and you scroll down the sheet so that the header row disappears, the column letters in the worksheet are replaced by the table headers.

• When you place a formula in any cell in a column of the table, it gets propagated to all the cells in that column.

• You can use table name and column header names in the formulas, without having to use cell references or creating range names.

• You can extend the table size by adding more rows or more columns by clicking and dragging the small triangular control at the lower-right corner of the lower-right cell.

• You can create and use slicers for a table for filtering data.

You will learn about all these Features in this Chapter.

Create Table

To create a table from the data you have on the worksheet, follow the given steps −

Step 1 − Select the Range of Cells that you want to include in the Table. Cells can contain data or can be empty. The following Range has 290 rows of employee data. The top row of the data has headers.

Step 2 − Under the Insert tab, in the Tables group, click Tables. The Create Table dialog box appears. Check that the data range selected in the Where is the data for your table? Box is correct.

Step 3 − Check the My table has headers box if the top row of the selected Range contains data that you want to use as the Table Headers.

Note − If you do not check this box, your table will have Headers – Column1, Column2, …

Step 4 − Click OK.

Range is converted to Table with the default Style.

Step 5 − You can also convert a range to a table by clicking anywhere on the range and pressing Ctrl+T. A Create Table dialog box appears and then you can repeat the steps as given above.

Table Name

Excel assigns a name to every table that is created.

Step 1 − To look at the name of the table you just created, click table, click on table tools – design tab on the Ribbon.

Step 2 − In the Properties group, in the Table Name box, your Table Name will be displayed.

Step 3 − You can edit this Table Name to make it more meaningful to your data.

Step 4 − Click the Table Name box. Clear the Name and type Emp_Data.

Note − The syntax rules of range names are applicable to table names.

Managing Names in a Table

You can manage table names just similar to how you manage range names with Name Manager.

• Click the Table.

• Click Name Manager in the Defined Names group on Formulas tab.

The Name Manager dialog box appears and you can find the Table Names in your workbook.

You can Edit a Table Name or add a comment with New option in the Name Manager dialog box. However, you cannot change the range in Refers to.

You can Create Names with column headers to use them in formulas, charts, etc.

• Click the Column Header EmployeeID in the Table.

• Click Name Manager.

• Click New in the Name Manager dialog box.

The New Name dialog box appears.

In the Name box, you can find the Column Header, and in the Refers to box,you will find Emp_Data[[#Headers],[EmployeeID]].

As you observe, this is a quick way of defining Names in a Table.

Table Headers replacing Column Letters

When you are working with more number of rows of data in a table, you may have to scroll down to look at the data in those rows.

However, while doing so, you also require the table headers to identify which value belongs to which column. Excel automatically provides a smooth way of doing this. As you scroll down your data, the column letters of the worksheet themselves get converted to table headers.

In the worksheet given below, the column letters are appearing as they are and the table headers are in row 2. 21 rows of 290 rows of data are visible.

Scroll down to see the table rows 25 – 35. The table headers will replace the column letters for the table columns. Other column letters remain as they are.

Propagation of a Formula in a Table

In the table given below, suppose you want to include the age of each employee.

Step 1 − Insert a column to the right of the column Birthdate. Type Age in the Column Header.

Step 2 − In any of the Cells in that empty column, type the Formula, =DAYS ([@BirthDate], TODAY ()) and Press Enter.

The formula propagates automatically to the other cells in that column of the table.

Resize Table

You can resize a table to add or remove rows/columns.

Consider the following table Student_Marks that contains Total Marks for Batches 1 — 15.

Suppose you want to add three more batches 16 – 18 and a column containing pass percentage.

• Click the table.

• Drag the blue-color control at the lower-right, downwards to include three more rows in the table.

• Again drag the blue-color control at the lower-right, sideways to include one more column in the table.

Your table looks as follows. You can also check the range included in the table in the Name Manager dialog box −

Remove Duplicates

When you gather data from different sources, you probably can have duplicate values. You need to remove the duplicate values before going further with analysis.

Look at the following data where you have information about various products of various brands. Suppose, you want to remove duplicates from this data.

• Click the table.

• On the DESIGN tab, click Remove Duplicates in the Tools group on the Ribbon. The Remove Duplicates dialog box appears.

The column headers appear under columns in the Remove Duplicates dialog box.

• Check the column headers depending on which column you want to remove the duplicates and click OK.

You will get a message on how many rows with duplicate values are removed and how many unique values remain. The cleaned data will be displayed in the table.

You can also remove duplicates with Remove Duplicates in the Data Tools group under DATA tab on the Ribbon.

Convert to Range

You can convert a table to a Range.

• Click the table.

• Click Convert to Range in the Tools group, under the Design tab on the Ribbon.

You will get a message asking you if you want to convert the table to a Range. After you confirm with Yes, the table will be converted to Range.

Table Style Options

You have several options of Table Styles to choose. These options can be used if you need to highlight a Row / Column.

You can check / uncheck these boxes to see how your table looks. Finally, you can decide on what options suit your data.

It is advised that the Table Style Options be used only to project important information in your data rather than making it colorful, which is not needed in data analysis.

Table Styles

You have several table styles to choose from. These styles can be used depending on what color and pattern you want to display your data in the table.

Move your mouse on these styles to have a preview of your table with the styles. Finally, you can decide on what style suit your data.

It is advised that the Table Styles be used only to project important information in your data in a presentable way rather than making it colorful, which is not needed in data analysis.

Slicers for Tables

If you are using Excel 2013 or Excel 2016, you can use Slicers for filtering data in your table.

For details on how to use Slicers for Tables, refer the chapter on Filtering in this tutorial.

Cleaning Data with Text Functions

The data that you obtain from different sources many not be in a form ready for analysis. In this chapter, you will understand how to prepare your data that is in the form of text for analysis.

Initially, you need to clean the data. Data cleaning includes removing unwanted characters from text. Next, you need to structure the data in the form you require for further analysis. You can do the same by −

• Finding required text patterns with the text functions.
• Extracting data values from text.
• Formatting data with text functions.
• Executing data operations with the text functions.

Removing Unwanted Characters from Text

When you import data from another application, it can have nonprintable characters and/or excess spaces. The excess spaces can be −

• leading spaces, and/or
• extra spaces between words.

If you sort or analyze such data, you will get erroneous results.

Consider the following example −

This is the raw data that you have obtained on product information containing the Product ID, Product description and the price. The character “|” separates the field in each row.

When you import this data into Excel worksheet, it looks as follows −

As you observe, the entire data is in a single column. You need to structure this data to perform data analysis. However, initially you need to clean the data.

You need to remove any nonprintable characters and excess spaces that might be present in the data. You can use the CLEAN function and TRIM function for this purpose.

S.No.	Function & Description
1.	CLEAN Removes all nonprintable characters from text
2.	TRIM Removes spaces from text

• Select the Cells C3 – C11.
• Type =TRIM (CLEAN (B3)) and then press CTRL + Enter.

The formula is filled in the cells C3 – C11.

The result will be as shown below −

Finding required Text Patterns with the Text Functions

To structure your data, you might have to do certain Text Pattern matching based on which you can extract the Data Values. Some of the Text Functions that are useful for this purpose are −

S.No.	Function & Description
1.	EXACT Checks to see if two text values are identical
2.	FIND Finds one text value within another (case-sensitive)
3.	SEARCH Finds one text value within another (not case-sensitive)

Extracting Data Values from Text

You need to extract the required data from text in order to structure the same. In the above example, say, you need to place the data in three columns – ProductID, Product_Description and Price.

You can extract data in one of the following ways −

• Extracting Data Values with Convert Text to Columns Wizard
• Extracting Data Values with Text Functions
• Extracting Data Values with Flash Fill

Extracting Data Values with Convert Text to Columns Wizard

You can use the Convert Text to Columns Wizard to extract Data Values into Excel columns if your fields are −

• Delimited by a character, or
• Aligned in columns with spaces between each field.

In the above example, the fields are delimited by the character “|”. Hence, you can use the Convert Text to Columns wizard.

• Select the data.

• Copy and paste values in the same place. Otherwise, Convert Text to Columns takes the functions rather than the data itself as the input.

• Select the data.

• Click on Text to Columns in the Data Tools group under Data Tab on the Ribbon.

Step 1 − Convert Text to Columns Wizard — Step 1 of 3 appears.

• Select Delimited.
• Click Next.

Step 2 − Convert Text to Columns Wizard — Step 2 of 3 appears.

• Under Delimiters, select Other.

• In the box next to Other, type the character |

• Click Next.

Step 3 − Convert Text to Columns Wizard — Step 3 of 3 appears.

In this screen, you can select each column of your data in the wizard and set the format for that column.

• For Destination, select the cell D3.

• You can click Advanced, and set Decimal Separator and Thousands Separator in the Advanced Text Import Settings dialog box that appears.

• Click Finish.

Your data, which is converted to columns appears in the three Columns – D, E and F.

• Name the Column headers as ProductID, Product_Description and Price.

Extracting Data Values with Text Functions

Suppose the fields in your data neither are delimited by a character nor are aligned in columns with spaces between each field, you can use text functions to extract data values. Even in the case the fields are delimited, you can still use text functions to extract data.

Some of the text functions that are useful for this purpose are −

S.No.	Function & Description
1.	LEFT Returns the leftmost characters from a text value
2.	RIGHT Returns the rightmost characters from a text value
3.	MID Returns a specific number of characters from a text string starting at the position you specify
4.	LEN Returns the number of characters in a text string

You can also combine two or more of these text functions as per the data you have at hand, to extract the required data values. For example, using a combination of LEFT, RIGHT and VALUE functions or using a combination of FIND, LEFT, LEN and MID functions.

In the above example,

• All the characters left to the first | give the name ProductID.

• All the characters right to the second | give the name Price.

• All the characters that lie between the first | and second | give the name Product_Description.

• Each | has a space before and after.

Observing this information, you can extract the data values with the following steps −

• Find the Position of First | — First | Position

  • You can use FIND function

• Find the Position of Second | — Second | Position

  • You can use FIND function again

• Beginning to (First | Position – 2) Characters of the Text give ProductID

  • You can use LEFT Function

• (First | Position + 2) to (Second | Position — 2) Characters of the Text give Product_Description

  • You can use MID Function

• (Second | Position + 2) to End Characters of the Text give Price

  • You can use RIGHT Function

The result will be as shown below −

You can observe that the values in the price column are text values. To perform calculations on these values, you have to format the corresponding cells. You can look at the section given below to understand formatting text.

Extracting Data Values with Flash Fill

Using Excel Flash Fill is another way to extract data values from text. However, this works only when Excel is able to find a pattern in the data.

Step 1 − Create three columns for ProductID, Product_Description and Price next to the data.

Step 2 − Copy and paste the values for C3, D3 and E3 from B3.

Step 3 − Select cell C3 and click Flash Fill in the Data Tools group on the Data tab. All the values for ProductID get filled.

Step 4 − Repeat the above given steps for Product_Description and Price. The data is filled.

Formatting Data with Text Functions

Excel has several built-in text functions that you can use for formatting data containing text. These include −

Functions that format the Text as per your need −

S.No.	Function & Description
1.	LOWER Converts text to lowercase

S.No.	Function & Description
1.	UPPER Converts text to uppercase
2.	PROPER Capitalizes the first letter in each word of a text value

Functions that convert and/or format the Numbers as Text −

S.No.	Function & Description
1.	DOLLAR Converts a number to text, using the $ (dollar) currency format
2.	FIXED Formats a number as text with a fixed number of decimals
3.	TEXT Formats a number and converts it to text

Functions that convert the Text to Numbers −

S.No.	Function & Description
1.	VALUE Converts a text argument to a number

Executing Data Operations with the Text Functions

You might have to perform certain Text Operations on your Data. For example, if Login-IDs for the Employees are changed to a New Format in an Organization, based on the Format Change, Text Replacements might have to be done.

Following Text Functions help you in performing Text Operations on your data containing Text −

S.No.	Function & Description
1.	REPLACE Replaces characters within text
2.	SUBSTITUTE Substitutes new text for old text in a text string
3.	CONCATENATE Joins several text items into one text item
4.	CONCAT Combines the text from multiple ranges and/or strings, but it does not provide the delimiter or IgnoreEmpty arguments.
5.	TEXTJOIN Combines the text from multiple ranges and/or strings, and includes a delimiter you specify between each text value that will be combined. If the delimiter is an empty text string, this function will effectively concatenate the ranges.
6.	REPT Repeats text a given number of times

Cleaning Data Containing Date Values

The data that you obtain from different sources might contain date values. In this chapter, you will understand how to prepare your data that contains data values for analysis.

You will learn about −

• Date Formats
  • Date in Serial Format
  • Date in different Month-Day-Year Formats
• Converting Dates in Serial Format to Month-Day-Year Format
• Converting Dates in Month-Day-Year Format to Serial Format
• Obtaining Today’s Date
• Finding a Workday after specified Days
• Customizing the Definition of a Weekend
• Number of Workdays between two given Dates
• Extracting Year, Month, Day from Date
• Extracting Day of the Week from Date
• Obtaining Date from Year, Month and Day
• Calculating Number of Years, Months and Days between two Dates

Date Formats

Excel supports Date values in two ways −

• Serial Format
• In different Year-Month-Day Formats

You can convert −

• A Date in Serial Format to a Date in Year-Month-Day Format

• A Date in Year-Month-Day Format to a Date in Serial Format

Date in Serial Format

A Date in serial format is a positive integer that represents the number of days between the given date and January 1, 1900. Both the current Date and January 1, 1900 are included in the count. For example, 42354 is a Date that represents 12/16/2015.

Date in Month-Day-Year Formats

Excel supports different Date Formats based on the Locale (Location) you choose. Hence, you need to first determine the compatibility of your Date formats and the Data Analysis at hand. Note that certain Date formats are prefixed with *(asterisk) −

• Date formats that begin with *(asterisk) respond to changes in regional date and time settings that are specified for the operating system

• Date formats without an *(asterisk) are not affected by operating system settings

For understanding purpose, you can assume United States as the Locale. You find the following Date formats to choose for the Date — 8^th June, 2016 −

• *6/8/2016 (affected by operating system settings)
• *Wednesday, June 8, 2016 (affected by operating system settings)
• 6/8
• 6/8/16
• 06/08/16
• 8-Jun
• 8-Jun-16
• 08-Jun-16
• Jun-16
• June-16
• J
• J-16
• 6/8/2016
• 8-Jun-2016

If you enter only two digits to represent a year and if −

• The digits are 30 or higher, Excel assumes the digits represent years in the twentieth century.

• The digits are lower than 30, Excel assumes the digits represent years in the twenty-first century.

For example, 1/1/29 is treated as January 1, 2029 and 1/1/30 is treated as January 1, 1930.

Converting Dates in Serial Format to Month-Day-Year Format

To convert dates from serial format to Month-Day-Year format, follow the steps given below −

• Click the Number tab in the Format Cells dialog box.

• Click Date under Category.

• Select Locale. The available Date formats will be displayed as a list under Type.

• Click on a Format under Type to look at the preview in the box adjacent to Sample.

After choosing the Format, click OK.

Converting Dates in Month-Day-Year Format to Serial Format

You can convert dates in Month-Day-Year format to Serial format in two ways −

• Using Format Cells dialog box

• Using Excel DATEVALUE function

Using Format Cells dialog box

• Click the Number tab in the Format Cells dialog box.

• Click General under Category.

Using Excel DATEVALUE Function

You can use Excel DATEVALUE function to convert a Date to Serial Number format. You need to enclose the Date argument in “”. For example,

=DATEVALUE («6/8/2016») results in 42529

Obtaining Today’s Date

If you need to perform calculations based on today’s date, simply use the Excel function TODAY (). The result reflects the date when it is used.

The following screenshot of TODAY () function usage has been taken on 16^th May, 2016 −

Finding a Workday after Specified Days

You might have to perform certain calculations based on your workdays.

Workdays exclude weekend days and any holidays. This means if you can define your weekend and holidays, whatever calculations you do will be based on workdays. For example, you can calculate invoice due dates, expected delivery times, the next meeting date, etc.

You can use Excel WORKDAY and WORKDAY.INTL functions for such operations.

S.No.	Function & Description
1.	WORKDAY Returns the serial number of the date before or after a specified number of workdays
2.	WORKDAY.INTL Returns the serial number of the date before or after a specified number of workdays using parameters to indicate which and how many days are weekend days

For example, you can specify the 15^th working day from today (the screenshot below is taken on 16^th May 2016) using the Functions TODAY and WORKDAY.

Suppose 25^th May 2016 and 1^st June 2016 are holidays. Then, your calculation will be as follows −

Customizing the Definition of a Weekend

By default, weekend is Saturday and Sunday, i.e. two days. You can also optionally define your weekend with the WORKDAY.INTL function. You can specify your own weekend by a weekend-number that corresponds to the weekend days as given in the table below. You need not remember these numbers, because when you start typing the function, you get a list of numbers and the weekend days in the drop-down list.

Weekend Days	Weekend-number
Saturday, Sunday	1 or omitted
Sunday, Monday	2
Monday, Tuesday	3
Tuesday, Wednesday	4
Wednesday, Thursday	5
Thursday, Friday	6
Friday, Saturday	7
Sunday only	11
Monday only	12
Tuesday only	13
Wednesday only	14
Thursday only	15
Friday only	16
Saturday only	17

Suppose, if weekend is Friday only, you need to use the number 16 in the WORKDAY.INTL function.

Number of Workdays between two given Dates

There might be a requirement to calculate the number of workdays between two dates, for example, in the case of calculating payment to a contract employee who is paid on per day basis.

You can find the number of workdays between two dates with the Excel functions NETWORKDAYS and NETWORKDAYS.INTL. Just as in the case of WORKDAYS and WORKDAYS.INTL, NETWORKDAYS and NETWORKDAYS.INTL allow you to specify holidays and with NETWORKDAYS.INTL you can additionally specify the weekend.

S.No.	Function & Description
1.	NETWORKDAYS Returns the number of whole workdays between two dates
2.	NETWORKDAYS.INTL Returns the number of whole workdays between two dates using parameters to indicate which and how many days are weekend days

You can calculate the number of workdays between today and another date with the functions TODAY and NETWORKDAYS. In the screen shot given below, today is 16^th May 2016 and end date is 16^th June 2016. 25^th May 2016 and 1^st June 2016 are holidays.

Again, the weekend is assumed to be Saturday and Sunday. You can have your own definition for weekend and calculate the number of workdays between two dates with the NETWORKDAYS.INTL function. In the screen shot given below, only Friday is defined as weekend.

Extracting Year, Month, Day from Date

You can extract from each date in a list of dates, the corresponding day, month and year using the excel functions DAY, MONTH and YEAR.

For example, consider the following dates −

From each of these dates, you can extract day, month and year as follows −

Extracting Day of the Week from Date

You can extract from each date in a list of dates, the corresponding day of the week with Excel WEEKDAY function.

Consider the same example given above.

Obtaining Date from Year, Month and Day

You data might have the information about Year, Month and Day separately. You need to get the date combining these three values to perform any calculation. You can use the DATE function for getting the date values.

Consider the following data −

Use the DATE function to obtain DATE values.

Calculating Years, Months and Days between two Dates

You might have to calculate the time lapsed from a given date. You might need this information in the form of years, months and days. A simple example would be calculating the current age of a person. It is effectively the difference between the birth date and today. You can use Excel DATEDIF, TODAY and CONCATENATE functions for this purpose.

The output is as follows −

Working with Time Values

The data that you obtain from different sources might contain time values. In this chapter, you will understand how to prepare your data that contains time values for analysis.

You will learn about −

• Time Formats
  • Time in Serial Format
  • Time in Hour-Minute-Second Format
• Converting Times in Serial Format to Hour-Minute-Second Format
• Converting Times in Hour-Minute-Second Format to Serial Format
• Obtaining the Current Time
• Obtaining Time from Hour, Minute and Second
• Extracting Hour, Minute and Second from Time
• Number of hours between Start Time and End Time

Time Formats

Excel supports Time Values in two ways −

• Serial Format
• In various Hour-Minute-Second Formats

You can convert −

• Time in Serial Format to Time in Hour-Minute-Second Format

• Time in Hour-Minute-Second Format to Time in Serial Format

Time in Serial Format

Time in serial format is a positive number that represents the Time as a fraction of a 24-hour day, the starting point being midnight. For example, 0.29 represents 7 AM and 0.5 represents 12 PM.

You can also combine Date and Time in the same cell. The serial number is the number of days after January 1, 1900, and the time fraction associated with the given time. For example, if you type May 17, 2016 6 AM, it gets converted to 42507.25 when you format the cell as General.

Time in Hour-Minute-Second Format

Excel allows you to specify time in Hour-Minute-Second Format with a colon (:) after the hour and another colon before the seconds. Example, 8:50 AM, 8:50 PM or just 8:50 using the 12-Hour Format or as 8:50, 20:50 in 24-Hour format. The time 8:50:55 AM represents 8 hours, 50 minutes and 55 seconds.

You can also specify date and time together. For example, if you type May 17, 2016 7:25 in a cell, it will be displayed as 5/17/2016 7:25 and it represents 5/17/2016 7:25:00 AM.

Excel supports different Time formats based on the Locale (Location) you choose. Hence, you need to first determine the compatibility of your Time formats and data analysis at hand.

For understanding purpose, you can assume United States as the Locale. You find the following Time formats to choose for Date and Time – 17^th May, 2016 4 PM −

• 4:00:00 PM
• 16:00
• 4:00 PM
• 16:00:00
• 5/17/16 4:00 PM
• 5/17/16 16:00

Converting Times in Serial Format to Hour-Minute-Second Format

To convert serial time format to hour-min-sec format follow the steps given below −

• Click the Number tab in the Format Cells dialog box

• Click Time under Category.

• Select the Locale. Available Time formats will be displayed as a list under Type.

• Click on a Format under Type to look at the Preview in the box adjacent to Sample.

After choosing the Format, click OK

Converting Times in Hour-Minute-Second Format to Serial Format

You can convert Time in Hour-Minute-Second format to serial format in two ways −

• Using Format Cells dialog box

• Using Excel TIMEVALUE function

Using Format Cells dialog box

• Click the Number tab in the Format Cells dialog box.

• Click General under Category.

Using Excel TIMEVALUE Function

You can use Excel TIMEVALUE function to convert Time to Serial Number format. You need to enclose the Time argument in “”. For example,

TIMEVALUE («16:55:15») results in 0.70503472

Obtaining the Current Time

If you need to perform calculations based on current time, simply use the Excel function NOW (). The result reflects the date and time when it is used.

The following screen shot of Now () function usage has been taken on 17^th May, 2016 at 12:22 PM.

Obtaining Time from Hour, Minute and Second

Your data might have the information about hours, minutes and seconds separately. Suppose, you need to get the Time combining these 3 values to perform any calculation. You can use Excel Function Time for getting the Time values.

Extracting Hour, Minute and Second from Time

You can extract hour, minute and second from a given time using the Excel functions HOUR, MINUTE and SECOND.

Number of hours between Start Time and End Time

When you perform computations on Time values, the result displayed depends on the format used in the cell. For example, you can compute the number of hours between 9:30 AM and 6 PM as follows −

• C4 is formatted as Time
• C5 and C6 are formatted as Number.

You get the time difference as days. To convert to hours you need to multiply by 24.

Excel Data Analysis — Conditional Formatting

In Microsoft Excel, you can use Conditional Formatting for data visualization. You have to specify formatting for a cell range based on the contents of the cell range. The cells that meet the specified conditions would be formatted as you have defined.

Example

In a range containing the sales figures of the past quarter for a set of salespersons, you can highlight those cells representing who have met the defined target, say, $2500.

You can set the condition as total sales of the person >= $2500 and specify a color code green. Excel checks each cell in the range to determine whether the condition you specified, i.e., total sales of the person >= $2500 is satisfied.

Excel applies the format you chose, i.e. the green color to all the cells that satisfy the condition. If the content of a cell does not satisfy the condition, the formatting of the cell remains unchanged. The result is as expected, only for the salespersons who have met the target, the cells are highlighted in green – a quick visualization of the analysis results.

You can specify any number of conditions for formatting by specifying Rules. You can pick up the rules that match your conditions from

• Highlight cells rules
• Top / Bottom rules

You can also define your own rules. You can −

• Add a rule
• Clear an existing rule
• Manage the defined rules

Further, you have several formatting options in Excel to choose the ones that are appropriate for your Data Visualization −

• Data Bars
• Color Scales
• Icon Sets

Conditional formatting has been promoted over the versions Excel 2007, Excel 2010, Excel 2013. The examples you find in this chapter are from Excel 2013.

In the following sections, you will understand the conditional formatting rules, formatting options and how to work with rules.

Highlight Cells Rules

You can use Highlight Cells rule to assign a format to cells whose contents meet any of the following criteria −

• Numbers within a given numerical range −
  • Greater Than
  • Less Than
  • Between
  • Equal To
• Text that contains a given text string.
• Date occurring within a given range of dates relative to the current date −
  • Yesterday
  • Today
  • Tomorrow
  • In the last 7 days
  • Last week
  • This week
  • Next week
  • Last month
  • This Month
  • Next month
• Values that are duplicate or unique.

Follow the steps to conditionally format cells −

• Select the range to be conditionally formatted.

• Click Conditional Formatting in the Styles group under Home tab.

• Click Highlight Cells Rules from the drop-down menu.

The data will be highlighted based on the given conditions and the corresponding formatting.

Top / Bottom Rules

You can use Top / Bottom Rules to assign a format to cells whose contents meet any of the following criteria −

• Top 10 items − Cells that rank in the top N, where 1 <= N <= 1000.

• Top 10% − Cells that rank in the top n%, where 1 <= n <= 100.

• Bottom 10 items − Cells that rank in the bottom N, where 1 <= N <= 1000.

• Bottom 10% − Cells that rank in the bottom n%, where 1 <= n <= 100.

• Above average − Cells that are above average for the selected range.

• Below average − Cells that are below average for the selected range.

Follow the steps given below to assign the Top/Bottom rules.

Data Bars

You can use colored Data Bars to see the value in a cell relative to the values in the other cells. The length of the data bar represents the value in the cell. A longer bar represents a higher value, and a shorter bar represents a lower value. You have six solid colors to choose from for the data bars – blue, green, red, yellow, light blue and purple.

Data bars are helpful in visualizing the higher, lower and intermediate values when you have large amounts of data. Example — Day temperatures across regions in a particular month. You can use gradient fill color bars to visualize the value in a cell relative to the values in other cells. You have six Gradient Colors to choose from for the Data Bars – Blue, Green, Red, Yellow, Light Blue and Purple.

• Select the range to be formatted conditionally.

You can also format data bars such that the data bar starts in the middle of the cell, and stretches to the left for negative values and stretches to the right for positive values.

Color Scales

You can use Color Scales to see the value in a cell relative to the values in the other cells in a given range. As in the case of Highlight Cells Rules, a Color Scale uses cell shading to display the differences in cell values. A color gradient will be applied to a range of cells. The color indicates where each cell value falls within that range.

You can choose from −

• Three — Color Scale −

Excel Data Analysis — Sorting

Sorting data is an integral part of Data Analysis. You can arrange a list of names in alphabetical order, compile a list of sales figures from highest to lowest, or order rows by colors or icons. Sorting data helps you quickly visualize and understand your data better, organize and find the data that you want, and ultimately make more effective decisions.

You can sort by columns or by rows. Most of the sorts that you use will be column sorts.

You can sort data in one or more columns by

• text (A to Z or Z to A)
• numbers (smallest to largest or largest to smallest)
• dates and times (oldest to newest and newest to oldest)
• a custom list (E.g. Large, Medium, and Small)
• format, including cell color, font color, or icon set

Sort criteria for a table are saved with the workbook such that you can reapply the sort to that table every time you open the workbook. Sort criteria are not saved for a range of cells. For multicolumn sorts or for sorts that take a long time to create, you can convert the range to a table. Then, you can reapply the sort when you open a workbook.

In all the examples in the following sections, you will find tables only, since it is more meaningful to sort a table.

The employee information where ManagerID = 2 OR Title = “*Specialist” is displayed.

Suppose you want to display information about specialists and vice presidents. You can define the criteria and filter as follows −

The criteria you applied is Title = “*Specialist” OR Title = “Vice President”. The employee information of specialists and vice presidents will be displayed.

You can copy the filtered data to another location. You can also select only few columns to include in the copy operation.

• Copy EmployeedID, Title and SalariedFlag to the Cells Q2, R2, S2. This will be the first Row of your filtered data.

• Click on Advanced and in the Advanced Filter dialog box, click on Copy to another location. In the Copy to box, specify reference to the Headers you copied in another location, i.e. Q2:S2.

Click OK after specifying the List Range and Criteria Range. The selected columns in the filtered data will be copied to the location you specified.

Filter Using Slicers

Slicers to filter data in PivotTables were introduced in Excel 2010. In Excel 2013, you can use Slicers to filter data in tables also.

Consider the data in the following table.

• Click the Table.
• Click Table Toolsthat appear on the Ribbon.
• The Design Ribbon appears.

A Slicer appears for each of the table headers you checked in the Insert Slicers dialog box. In each Slicer, all the values of that column will be highlighted.

In the Title Slicer, click the first value. Only that value will be highlighted and the rest of the values get unselected. Further, you will find the values in HireDate Slicer that are corresponding to the value in the Title Slicer also get highlighted.

In the table, only the selected values are displayed.

You can select / deselect the values in the Slicers and you find that the data is automatically updated in the table. To choose more than one value, hold down the Ctrl key, and pick the values that you want to display.

Select the Title values that belong to the Accounts department and the HireDate values in the year 2015 from the two Slicers.

You can clear the selections in any Slicer by clicking the Clear Filter at the right end corner of the Slicer header.

Excel Data Analysis — Subtotals with Ranges

If you have a list of data that you want to group and summarize, you can use Excel Subtotal and Outline to display summary rows or columns. You can use PivotTable also for this purpose, but using Subtotal and Outline is the quickest way to analyze a range of data. Note that Subtotal and Outline can be used only on a range and not on a table.

You can create an Outline of up to eight levels, one for each group. Outer Levels are represented by Lower Numbers and Inner Levels by Higher Numbers. Each inner level displays detailed data for the preceding outer level.

To understand how to use Subtotal and Outline, consider the following example wherein the sales data of various items is given salesperson wise and location wise. In total, there are 1891 rows of data.

Excel Data Analysis — Quick Analysis

In Microsoft Excel 2013, the Quick Analysis tool makes it possible to analyze your data quickly and easily using different Excel tools.

You can use Quick Analysis with a range or a table of data. To access Quick Access tool, select the cells that contain the data you want to analyze. The Quick Analysis tool button appears at the bottom right of your selected data.

Click the Quick Analysis button. The Quick Analysis toolbar appears with the options FORMATTING, CHARTS, TOTALS, TABLES, SPARKLINES.

Quick Analysis tool is handy and quick to use as you can also have a preview of applying different options, before selecting the one you want.

Formatting

Conditional Formatting allows you to highlight parts of your data by adding Data Bars, Colors, etc. This lets you quickly visualize the values in your data.

You have learnt about formatting rules in the Conditional Formatting chapter in this tutorial. The difference is that you can have a quick preview and select the option you want. However, if you want to utilize all the features of Conditional Formatting, you rather go through the main menu on the Ribbon. The same thing holds for all the options in the Quick Analysis tool.

Click Formatting on the Quick Analysis toolbar. The Conditional Formatting options appear in the toolbar. Move your mouse on the options. You will see the previews. You can then select the option you want by clicking it.

Charts

Charts are used to depict the data pictorially. There are several types of Charts to suit different types of data.

If you click CHARTS on the Quick Analysis toolbar, the recommended charts for the data you have selected will be displayed. You can always choose More Charts option if you want to go to the main Charts on the Ribbon.

Hover your mouse on the options. You will see the previews. You can then select the option you want by clicking it.

Totals

Totals can be used to calculate the numbers in columns and rows. You will have functions such as Sum, Average, Count, etc.

We will go into the details on how to use Quick Analysis tool with TOTALS later in this chapter. You can use the other options in Quick Analysis with the same ease, as you observe.

Tables

Tables help you to filter, sort and summarize your data, as you have already learnt in the Tables chapter. In the Quick Analysis tool, both the Table and PivotTable options are available under TABLES. However, you can have a preview for the table, but in the case of PivotTable no preview is available as by clicking you will get an empty PivotTable which you need to populate with the data.

Sparklines

Sparklines are tiny charts that you can show alongside your data in single cells. They provide a quick way to see trends.

Quick Analysis with TOTALS

Click on TOTALS in the Quick Analysis Toolbar.

In Quick Analysis with TOTALS, you can analyze

Row-wise

Column-wise

For row wise calculations, ensure that you have an empty row below the selected data.

Example

We will analyze the data of the votes polled in an election for five candidates. The counting is done in four rounds. Following is the data.

Sum

Select the data and Click on the Quick Analysis toolbar under TOTALS.

Ensure that the row below the data is empty. Otherwise, you will get a message saying that there is already data present there and you will only have two options, either replace the existing data or cancel the operation.

In the row below the selected data, the sum of each column of the data is displayed. The caption Sum is also automatically provided. This means the total count of votes in each round for all the candidates is displayed.

Average

Select the data and click on the Quick Analysis Toolbar under TOTALS.

The average of each column of the data appears in the row below the data. The caption Average is also automatically provided. The average number of votes polled in each round is displayed.

Count

Select the data and click on the Quick Analysis Toolbar under TOTALS.

The count of each column of the data appears in the row below the data. The caption Count is also automatically provided. This means the count of candidates in each round is displayed.

%Total

Select the data and click on the Quick Analysis Toolbar under TOTALS.

The %Total of each column of the data appears in the row below the data. The caption %Total is also automatically provided. This means the %Total of votes in each round is displayed.

Running Total

Select the data and Click on the Quick Analysis Toolbar under TOTALS.

The running total of each column of the data appears in the row below the data. The caption Running Total is also automatically provided. This means the running total of votes across the rounds is displayed.

Sum of Columns

Select the data and click on the Quick Analysis toolbar under TOTALS.

Ensure that the column next to the data is empty. Otherwise, you will get a message saying that there is already data present there and you will only have two options, either replace the existing data or cancel the operation.

In the column next to the selected data, the sum of each row of the data is displayed. The column header Sum is also automatically provided. This means the total number of votes polled for each candidate in all the rounds is displayed.

Excel Data Analysis — Lookup Functions

You can use Excel functions to −

• Find values in a range of data — VLOOKUP and HLOOKUP
• Obtain a value or the reference to a value from within a table or range — INDEX
• Obtain the relative position of a specified item in a range of cells — MATCH

You can also combine these functions to get the required results based on the inputs you have.

Using VLOOKUP Function

The syntax of the VLOOKUP function is

VLOOKUP (lookup_value, table_array, col_index_num, [range_lookup])

Where

• lookup_value − is the value you want to look up. Lookup_value can be a value or a reference to a cell. Lookup_value must be in the first column of the range of cells you specify in table_array

• table_array − is the range of cells in which the VLOOKUP will search for the lookup_value and the return value. table_array must contain

  • the lookup_value in the first column, and

  • the return value you want to find

    Note − The first column containing the lookup_value can either be sorted in ascending order or not. However, the result will be based on the order of this column.

• col_index_num − is the column number in the table_array that contains the return value. The numbers start with 1 for the left-most column of table-array

• range_lookup − is an optional logical value that specifies whether you want VLOOKUP to find an exact match or an approximate match. range_lookup can be

  • omitted, in which case it is assumed to be TRUE and VLOOKUP tries to find an approximate match

  • TRUE, in which case VLOOKUP tries to find an approximate match. In other words, if an exact match is not found, the next largest value that is less than lookup_value is returned

  • FALSE, in which case VLOOKUP tries to find an exact match

  • 1, in which case it is assumed to be TRUE and VLOOKUP tries to find an approximate match

  • 0, in which case it is assumed to be FALSE and VLOOKUP tries to find an exact match

Note − If range_lookup is omitted or TRUE or 1, VLOOKUP works correctly only when the first column in table_array is sorted in ascending order. Otherwise, it may result in incorrect values. In such a case, use FALSE for range_lookup.

Using VLOOKUP Function with range_lookup TRUE

Consider a list of student marks. You can obtain the corresponding grades with VLOOKUP from an array containing the marks intervals and pass category.

table_array −

Note that the first column marks based on which the grades are obtained is sorted in ascending order. Hence, using TRUE for range_lookup argument you can get approximate match that is what is required.

Name this array as Grades.

It is a good practice to name arrays in this way so that you need not remember the cell ranges. Now, you are ready to look up the grade for the list of marks you have as follows −

As you can observe,

• col_index_num − indicates the column of the return value in table_array is 2

• the range_lookup is TRUE

  • The first column containing the lookup value in the table_array grades is in ascending order. Hence, the results will be correct.

  • You can get the return value for approximate matches also. i.e. VLOOKUP computes as follows −

Marks	Pass Category
< 35	Fail
>= 35 and < 50	Third Class
>= 50 and < 60	Second Class
>=60 and < 75	First Class
>= 75	First Class with Distinction

You will get the following results −

Using VLOOKUP Function with range_lookup FALSE

Consider a list of products containing the Product ID and price for each of the products. The product ID and price will be added to the end of the list whenever a new product is launched. This would mean that the product IDs need not be in ascending order. The product list might be as shown below −

table_array −

Name this array as ProductInfo.

You can obtain the price of a product given the product ID with the VLOOKUP function as the product ID is in the first column. The price is in column 3 and hence col_index_ num should be 3.

• Use VLOOKUP Function with range_lookup as TRUE
• Use VLOOKUP Function with range_lookup as FALSE

The correct answer is from the ProductInfo array is 171.65. You can check the results.

You observe that you got −

• The correct result when range_lookup is FALSE, and
• A wrong result when range_lookup is TRUE.

This is because, the first column in the ProductInfo array is not sorted in ascending order. Hence, remember to use FALSE whenever the data is not sorted.

Using HLOOKUP Function

You can use HLOOKUP function if the data is in rows rather than columns.

Example

Let us take the example of product information. Suppose the array looks as follows −

• Name this Array ProductRange. You can find the price of a product given the product ID with HLOOKUP function.

The Syntax of HLOOKUP function is

HLOOKUP (lookup_value, table_array, row_index_num, [range_lookup])

Where

• lookup_value − is the value to be found in the first row of the table

• table_array − is a table of information in which data is looked up

• row_index_num − is the row number in table_array from which the matching value will be returned

• range_lookup − is a logical value that specifies whether you want HLOOKUP to find an exact match or an approximate match

• range_lookup can be

  • omitted, in which case it is assumed to be TRUE and HLOOKUP tries to find an approximate match

  • TRUE, in which case HLOOKUP tries to find an approximate match. In other words, if an exact match is not found, the next largest value that is less than lookup_value is returned

  • FALSE, in which case HLOOKUP tries to find an exact match

  • 1, in which case it is assumed to be TRUE and HLOOKUP tries to find an approximate match

  • 0, in which case it is assumed to be FALSE and HLOOKUP tries to find an exact match

Note − If range_lookup is Omitted or TRUE or 1, HLOOKUP works correctly only when the first column in table_array is sorted in ascending order. Otherwise, it may result in incorrect values. In such a case, use FALSE for range_lookup.

Using HLOOKUP Function with range_lookup FALSE

You can obtain the price of a product given the product ID with the HLOOKUP function as the product ID is in the first row. The price is in row 3 and hence row_index_ num should be 3.

• Use HLOOKUP Function with range_lookup as TRUE.
• Use HLOOKUP Function with range_lookup as FALSE.

The correct answer from the ProductRange array is 171.65. You can check the results.

You observe that as in the case of VLOOKUP, you got

• The correct result when range_lookup is FALSE, and

• A wrong result when range_lookup is TRUE.

This is because the first row in the ProductRange array is not sorted in ascending order. Hence, remember to use FALSE whenever the data is not sorted.

Using HLOOKUP Function with range_lookup TRUE

Consider the example of student marks used in VLOOKUP. Suppose you have the data in rows instead of columns as shown in the table given below −

table_array −

Name this array as GradesRange.

Note that the first row marks based on which the grades are obtained is sorted in ascending order. Hence, using HLOOKUP with TRUE for range_lookup argument, you can get the Grades with approximate match and that is what is required.

As you can observe,

• row_index_num − indicates the column of the return value in table_array is 2

• the range_lookup is TRUE

  • The first column containing the lookup value in the table_array Grades is in ascending order. Hence, the results will be correct.

  • You can get the return value for approximate matches also. i.e. HLOOKUP computes as follows −

Marks	< 35	>= 35 and < 50	>= 50 and < 60	>=60 and < 75	>= 75
Pass Category	Fail	Third Class	Second Class	First Class	First Class with Distinction

You will get the following results −

Using INDEX Function

When you have an array of data, you can retrieve a value in the array by specifying the row number and column number of that value in the array.

Consider the following sales data, wherein you find the sales in each of the North, South, East and West regions by the salespersons who are listed.

• Name the array as SalesData.

Using INDEX Function, you can find −

• The Sales of any of the Salespersons in a certain Region.
• Total Sales in a Region by all the Salespersons.
• Total Sales by a Salesperson in all the Regions.

You will get the following results −

Suppose you do not know the row numbers for the salespersons and column numbers for the regions. Then, you need to find the row number and column number first before you retrieve the value with the index function.

You can do it with the MATCH function as explained in the next section.

Using MATCH Function

If you need the position of an item in a range, you can use the MATCH function. You can combine MATCH and INDEX functions as follows −

You will get the following results −

Excel Data Analysis — PivotTables

Data analysis on a large set of data is quite often necessary and important. It involves summarizing the data, obtaining the needed values and presenting the results.

Excel provides PivotTable to enable you summarize thousands of data values easily and quickly so as to obtain the required results.

Consider the following table of sales data. From this data, you might have to summarize total sales region wise, month wise, or salesperson wise. The easy way to handle these tasks is to create a PivotTable that you can dynamically modify to summarize the results the way you want.

Creating PivotTable

To create PivotTables, ensure the first row has headers.

• Click the table.
• Click the INSERT tab on the Ribbon.
• Click PivotTable in the Tables group. The PivotTable dialog box appears.

As you can see in the dialog box, you can use either a Table or Range from the current workbook or use an external data source.

• In the Table / Range Box, type the table name.
• Click New Worksheet to tell Excel where to keep the PivotTable.
• Click OK.

A Blank PivotTable and a PivotTable fields list appear.

Recommended PivotTables

In case you are new to PivotTables or you do not know which fields to select from the data, you can use the Recommended PivotTables that Excel provides.

• Click the data table.

• Click the INSERT tab.

• Click on Recommended PivotTables in the Tables group. The Recommended PivotTables dialog box appears.

In the recommended PivotTables dialog box, the possible customized PivotTables that suit your data are displayed.

• Click each of the PivotTable options to see the preview on the right side.
• Click the PivotTable Sum of Order Amount by Salesperson and month.

Click OK. The selected PivotTable appears on a new worksheet. You can observe the PivotTable fields that was selected in the PivotTable fields list.

PivotTable Fields

The headers in your data table will appear as the fields in the PivotTable.

You can select / deselect them to instantly change your PivotTable to display only the information you want and in a way that you want. For example, if you want to display the account information instead of order amount information, deselect Order Amount and select Account.

PivotTable Areas

You can even change the Layout of your PivotTable instantly. You can use the PivotTable Areas to accomplish this.

In PivotTable areas, you can choose −

• What fields to display as rows
• What fields to display as columns
• How to summarize your data
• Filters for any of the fields
• When to update your PivotTable Layout
  • You can update it instantly as you drag the fields across areas, or
  • You can defer the update and get it updated only when you click on UPDATE

An instant update helps you to play around with the different Layouts and pick the one that suits your report requirement.

You can just drag the fields across these areas and observe the PivotTable layout as you do it.

Nesting in the PivotTable

If you have more than one field in any of the areas, then nesting happens in the order you place the fields in that area. You can change the order by dragging the fields and observe how nesting changes. In the above layout options, you can observe that

• Months are in columns.
• Region and salesperson in rows in that order. i.e. salesperson values are nested under region values.
• Summarizing is by Sum of Order Amount.
• No filters are chosen.

The resulting PivotTable is as follows −

In the PivotTable Areas, in rows, click region and drag it below salesperson such that it looks as follows −

The nesting order changes and the resulting PivotTable is as follows −

Note − You can clearly observe that the layout with the nesting order – Region and then Salesperson yields a better and compact report than the one with the nesting order – Salesperson and then Region. In case Salesperson represents more than one area and you need to summarize the sales by Salesperson, then the second layout would have been a better option.

Filters

You can assign a Filter to one of the fields so that you can dynamically change the PivotTable based on the values of that field.

Drag Region from Rows to Filters in the PivotTable Areas.

The filter with the label as Region appears above the PivotTable (in case you do not have empty rows above your PivotTable, PivotTable gets pushed down to make space for the Filter.

You can see that −

• Salesperson values appear in rows.
• Month values appear in columns.
• Region Filter appears on the top with default selected as ALL.
• Summarizing value is Sum of Order Amount
  • Sum of Order Amount Salesperson-wise appears in the column Grand Total
  • Sum of Order Amount Month-wise appears in the row Grand Total

Click the arrow in the box to the right of the filter region. A drop-down list with the values of the field region appears.

• Check the option Select Multiple Items. Check boxes appear for all the values.
• Select South and West and deselect the other values and click OK.

The data pertaining to South and West Regions only will be summarized as shown in the screen shot given below −

You can see that next to the Filter Region, Multiple Items is displayed, indicating that you have selected more than one item. However, how many items and / or which items are selected is not known from the report that is displayed. In such a case, using Slicers is a better option for filtering.

Slicers

You can use Slicers to have a better clarity on which items the data was filtered.

• Click ANALYZE under PIVOTTABLE TOOLS on the Ribbon.

• Click Insert Slicer in the Filter group. The Insert Slicers box appears. It contains all the fields from your data.

• Select the fields Region and month. Click OK.

Slicers for each of the selected fields appear with all the values selected by default. Slicer Tools appear on the Ribbon to work on the Slicer settings, look and feel.

• Select South and West in the Slicer for Region.
• Select February and March in the Slicer for month.
• Keep Ctrl key pressed while selecting multiple values in a Slicer.

Selected items in the Slicers are highlighted. PivotTable with summarized values for the selected items will be displayed.

Summarizing Values by other Calculations

In the examples so far, you have seen summarizing values by Sum. However, you can use other calculations also if necessary.

In the PivotTable Fields List

• Select the Field Account.
• Unselect the Field Order Amount.

• Drag the field Account to Summarizing Values area. By default, Sum of Account will be displayed.
• Click the arrow on the right side of the box.
• In the drop-down that appears, click Value Field Settings.

The Value Field Settings box appears. Several types of calculations appear as a list under Summarize value field by −

• Select Count in the list.
• The Custom Name automatically changes to Count of Account. Click OK.

The PivotTable summarizes the Account values by Count.

PivotTable Tools

Follow the steps given below to learn to use the PivotTable Tools.

• Select the PivotTable.

The following PivotTable Tools appear on the Ribbon −

• ANALYZE
• DESIGN

ANALYZE

Some of the ANALYZE Ribbon commands are −

• Set PivotTable Options
• Value Field Settings for the selected Field
• Expand Field
• Collapse Field
• Insert Slicer
• Insert Timeline
• Refresh Data
• Change Data Source
• Move PivotTable
• Solve Order (If there are more calculations)
• PivotChart

DESIGN

Some of the DESIGN Ribbon commands are −

• PivotTable Layout
  • Options for Sub Totals
  • Options for Grand Totals
  • Report Layout Forms
  • Options for Blank Rows
• PivotTable Style Options
• PivotTable Styles

Expanding and Collapsing Field

You can either expand or collapse all items of a selected field in two ways −

By selecting the Expand symbol or Collapse symbol to the left of the selected field

• Select the cell containing East in the PivotTable.
• Click on the Collapse symbol to the left of East.

All the items under East will be collapsed. The Collapse symbol to the left of East changes to the Expand symbol .

You can observe that only the items below East are collapsed. The rest of the PivotTable items are as they are.

Click the Expand symbol to the left of East. All the items below East will be displayed.

Using ANALYZE on the Ribbon

You can collapse or expand all items in the PivotTable at once with the Expand Field and Collapse Field commands on the Ribbon.

• Click the cell containing East in the PivotTable.
• Click the ANALYZE tab on the Ribbon.
• Click Collapse Field in the Active Field group.

All the items of the field East in the PivotTable will collapse.

Click Expand Field in the Active Field group.

All the items will be displayed.

Report Presentation Styles

You can choose the presentation style for your PivotTable as you would be including it as a report. Select a style that fits into the rest of your presentation or report. However, do not get over bored with the styles because a report that gives an impact in showing the results is always better than a colorful one, which does not highlight the important data points.

• Click East in the PivotTable.
• Click ANALYZE.
• Click Field Settings in Active Field group. The Field Settings dialog box appears.
• Click the Layout & Print tab.
• Check Insert blank line after each item label.

Blank rows will be displayed after each value of the Region field.

You can insert blank rows from the DESIGN tab also.

• Click the DESIGN tab.
• Click Report Layout in Layout group.

• Hover the mouse over the PivotTable Styles. A preview of the style on which the mouse is placed will appear.
• Select the Style that suits your report.

PivotTable in Outline Form with the selected Style will be displayed.

Timeline in PivotTables

To understand how to use Timeline, consider the following example wherein the sales data of various items is given salesperson wise and location wise. There are total 1891 rows of data.

Create a PivotTable from this Range with −

• Location and Salesperson in Rows in that order
• Product in Columns
• Sum of Amount in Summarizing values

• Click the PivotTable.
• Click INSERT tab.
• Click Timeline in Filters group. The Insert Timelines appears.

Click Date and click OK. The Timeline dialog box appears and the Timeline Tools appear on the Ribbon.

• In Timeline dialog box, select MONTHS.
• From the drop-down list select QUARTERS.
• Click 2014 Q2.
• Keep the Shift key pressed and drag to 2014 Q4.

Timeline is selected to Q2 – Q4 2014.

PivotTable is filtered to this Timeline.

Excel Data Analysis — Data Visualization

You can display your data analysis reports in a number of ways in Excel. However, if your data analysis results can be visualized as charts that highlight the notable points in the data, your audience can quickly grasp what you want to project in the data. It also leaves a good impact on your presentation style.

In this chapter, you will get to know how to use Excel charts and Excel formatting features on charts that enable you to present your data analysis results with emphasis.

Visualizing Data with Charts

In Excel, charts are used to make a graphical representation of any set of data. A chart is a visual representation of the data, in which the data is represented by symbols such as bars in a Bar Chart or lines in a Line Chart. Excel provides you with many chart types and you can choose one that suits your data or you can use the Excel Recommended Charts option to view charts customized to your data and select one of those.

Refer to the Tutorial Excel Charts for more information on chart types.

In this chapter, you will understand the different techniques that you can use with the Excel charts to highlight your data analysis results more effectively.

Creating Combination Charts

Suppose you have the target and actual profits for the fiscal year 2015-2016 that you obtained from different regions.

We will create a Clustered Column Chart for these results.

As you observe, it is difficult to visualize the comparison quickly between the targets and actual in this chart. It does not give a true impact on your results.

A better way of distinguishing two types of data to compare the values is by using Combination Charts. In Excel 2013 and versions above, you can use Combo charts for the same purpose.

Use Vertical Columns for the target values and a Line with Markers for the actual values.

• Click the DESIGN tab under the CHART TOOLS tab on the Ribbon.
• Click Change Chart Type in the Type group. The Change Chart Type dialog box appears.

• Click Combo.

• Change the Chart Type for the series Actual to Line with Markers. The preview appears under Custom Combination.

• Click OK.

Your Customized Combination Chart will be displayed.

As you observe in the chart, the Target values are in Columns and the Actual values are marked along the line. The data visualization has become better as it also shows you the trend of your results.

However, this type of representation does not work well when the data ranges of your two data values vary significantly.

Creating a Combo Chart with Secondary Axis

Suppose you have the data on the number of units of your product that was shipped and the actual profits for the fiscal year 2015-2016 that you obtained from different regions.

If you use the same combination chart as before, you will get the following −

In the chart, the data of No. of Units is not visible as the data ranges are varying significantly.

In such cases, you can create a combination chart with secondary axis, so that the primary axis displays one range and the secondary axis displays the other.

• Click the INSERT tab.
• Click Combo in Charts group.
• Click Create Custom Combo Chart from the drop-down list.

The Insert Chart dialog box appears with Combo highlighted.

For Chart Type, choose −

• Line with Markers for the Series No. of Units
• Clustered Column for the Series Actual Profits
• Check the Box Secondary Axis to the right of the Series No. of Units and click OK.

A preview of your chart appears under Custom Combination.

Your Combo chart appears with Secondary Axis.

You can observe the values for Actual Profits on the primary axis and the values for No. of Units on the secondary axis.

A significant observation in the above chart is for Quarter 3 where No. of Units sold is more, but the Actual Profits made are less. This could probably be assigned to the promotion costs that were incurred to increase sales. The situation is improved in Quarter 4, with a slight decrease in sales and a significant rise in the Actual Profits made.

Discriminating Series and Category Axis

Suppose you want to project the Actual Profits made in Years 2013-2016.

Create a clustered column for this data.

As you observe, the data visualization is not effective as the years are not displayed. You can overcome this by changing year to category.

Remove the header year in the data range.

Now, year is considered as a category and not a series. Your chart looks as follows −

Chart Elements and Chart Styles

Chart Elements give more descriptions to your charts, thus helping visualizing your data more meaningfully.

• Click the Chart

Three buttons appear next to the upper-right corner of the chart −

For a detailed explanation of these, refer to Excel Charts tutorial.

• Click Chart Elements.
• Click Data Labels.

• Click Chart Styles
• Select a Style and Color that suits your data.

You can use Trendline to graphically display trends in data. You can extend a Trendline in a chart beyond the actual data to predict future values.

Data Labels

Excel 2013 and later versions provide you with various options to display Data Labels. You can choose one Data Label, format it as you like, and then use Clone Current Label to copy the formatting to the rest of the Data Labels in the chart.

The Data Labels in a chart can have effects, varying shapes and sizes.

It is also possible to display the content of a cell as part of the Data Label with Insert Data Label Field.

Quick Layout

You can use Quick Layout to change the overall layout of the chart quickly by choosing one of the predefined layout options.

• Click the chart.
• Click the DESIGN tab under CHART TOOLS.
• Click Quick Layout.

Different possible layouts will be displayed. As you move on the layout options, the chart layout changes to that particular option.

Select the layout you like. The chart will be displayed with the chosen layout.

Using Pictures in Column Charts

You can create more emphasis on your data presentation by using a picture in place of columns.

• Click on a Column on the Column Chart.

• In the Format Data Series, click on Fill.

• Select Picture.

• Under Insert picture from, provide the filename or optionally clipboard if you had copied an image earlier.

The picture you have chosen will appear in place of columns in the chart.

Band Chart

You might have to present customer survey results of a product from different regions. Band Chart is suitable for this purpose. A Band Chart is a Line Chart with an added shaded area to display the upper and lower boundaries of groups of data.

Suppose your customer survey results from the east and west regions, month wise are −

Here, in the data < 50% is Low, 50% — 80% is Medium and > 80% is High.

With Band Chart, you can display your survey results as follows −

Create a Line Chart from your data.

Change the chart type to −

• East and West Series to Line with Markers.
• Low, Medium and High Series to Stacked Column.

Your chart looks as follows.

• Click on one of the columns.
• Change gap width to 0% in Format Data Series.

You will get Bands instead of columns.

To make the chart more presentable −

• Add Chart Title.
• Adjust Vertical Axis range.
• Change the colors of the bands to Green-Yellow-Red.
• Add Labels to bands.

The final result is the Band Chart with the defined boundaries and the survey results represented across the bands. One can quickly and clearly make out from the chart that while the survey results for the region West are satisfactory, those for the region East have a decline in the last quarter and need attention.

Thermometer Chart

When you have to represent a target value and an actual value, you can easily create a Thermometer Chart in Excel that emphatically shows these values.

With Thermometer chart, you can display your data as follows −

Arrange your data as shown below −

• Select the data.
• Create a Clustered Column chart.

As you observe, the right side Column is Target.

Gantt Chart

A Gantt chart is a chart in which a series of horizontal lines shows the amount of work done in certain periods of time in relation to the amount of work planned for those periods.

In Excel, you can create a Gantt chart by customizing a Stacked Bar chart type so that it depicts tasks, task duration, and hierarchy. An Excel Gantt chart typically uses days as the unit of time along the horizontal axis.

Consider the following data where the column −

• Task represents the Tasks in the project
• Start represents number of days from the Start Date of the project
• Duration represents the duration of the Task

Note that Start of any Task is Start of previous Task + Duration. This is the case when the Tasks are in hierarchy.

• Select the data.
• Create Stacked Bar Chart.

• Right-click on Start Series.
• In Format Data Series options, select No fill.

• Right-click on Categories Axis.
• In Format Axis options, select Categories in reverse order.

• In Chart Elements, deselect
  • Legend
  • Gridlines

  • Adjust the range
  • Major Tick Marks at 5 day intervals
  • Minor Tick Marks at 1 day intervals
• Format Data Series to make it look impressive
• Give a Chart Title

Waterfall Chart

Waterfall Chart is one of the most popular visualization tools used in small and large businesses. Waterfall charts are ideal for showing how you have arrived at a net value such as net income, by breaking down the cumulative effect of positive and negative contributions.

Excel 2016 provides Waterfall Chart type. If you are using earlier versions of Excel, you can still create a Waterfall Chart using Stacked Column Chart.

The columns are color coded so that you can quickly tell positive from negative numbers. The initial and the final value columns start on the horizontal axis, while the intermediate values are floating columns. Because of this look, Waterfall Charts are also called Bridge Charts.

Consider the following data.

• Prepare the data for Waterfall Chart

• Ensure the column Net Cash Flow is to the left of the Months Column (This is because you will not include this column while creating the chart)

• Add 2 columns – Increase and Decrease for positive and negative cash flows respectively

• Add a column Start — the first column in the chart with the start value in the Net Cash Flow

• Add a column End — the last column in the chart with the end value in the Net Cash Flow

• Add a column Float – that supports the intermediate columns

• Compute the values for these columns as follows

• In the Float column, insert a row in the beginning and at the end. Place n arbitrary value 50000. This just to have some space to the left and right of the chart

The data will be as follows.

• Select the cells C2:H18 (Exclude Net Cash Flow column)
• Create Stacked Column Chart

• Right click on the Float Series.
• Click Format Data Series.
• In Format Data Series options, select No fill.

• Right click on Negative Series.
• Select Fill Color as Red.

• Right click on Positive Series.
• Select Fill Color as Green.

• Right click on Start Series.
• Select Fill Color as Grey.
• Right click on End Series.
• Select Fill Color as Grey.
• Delete the Legend.

• Right click on any Series
• In Format Data Series options, select Gap Width as 10% under Series Options

Give the Chart Title. The Waterfall Chart will be displayed.

Sparklines

Sparklines are tiny charts placed in single cells, each representing a row of data in your selection. They provide a quick way to see trends.

You can add Sparklines with Quick Analysis tool.

• Select the data for which you want to add Sparklines.
• Keep an empty column to the right side of the data for the Sparklines.

Quick Analysis button appears at the bottom right of your selected data.

• Click on the Quick Analysis button. The Quick Analysis Toolbar appears with various options.

Click SPARKLINES. The chart options displayed are based on the data and may vary.

Click Line. A Line Chart for each row is displayed in the column to the right of the data.

PivotCharts

Pivot Charts are used to graphically summarize data and explore complicated data.

A PivotChart shows Data Series, Categories, and Chart Axes the same way a standard chart does. Additionally, it also gives you interactive filtering controls right on the chart so that you can quickly analyze a subset of your data.

PivotCharts are useful when you have data in a huge PivotTable, or many complex worksheet data that includes text and numbers. A PivotChart can help you make sense of this data.

You can create a PivotChart from

• A PivotTable.
• A Data Table as a standalone without PivotTable.

PivotChart from PivotTable

To create a PivotChart follow the steps given below −

• Click the PivotTable.
• Click ANALYZE under PIVOTTABLE TOOLS on the Ribbon.
• Click on PivotChart. The Insert Chart dialog box appears.

Select Clustered Column from the option Column.

Click OK. The PivotChart is displayed.

The PivotChart has three filters – Region, Salesperson and Month.

• Click the Region Filter Control option. The Search Box appears with the list of all Regions. Check boxes appear next to Regions.

• Select East and South options.

The filtered data appears on both the PivotChart and the PivotTable.

PivotChart without a PivotTable

You can create a standalone PivotChart without creating a PivotTable.

• Click the Data Table.
• Click the Insert tab.
• Click PivotChart in Charts group. The Create PivotChart window appears.
• Select the Table/Range.
• Select the Location where you want the PivotChart to be placed.

You can choose a cell in the existing worksheet itself, or in a new worksheet. Click OK.

An empty PivotChart and an empty PivotTable appear along with the PivotChart Field List to build the PivotChart.

• Choose the Fields to be added to the PivotChart

• Arrange the Fields by dragging them into FILTERS, LEGEND (SERIES), AXIS (CATEGORIES) and VALUES

• Use the Filter Controls on the PivotChart to select the Data to be placed on the PivotChart

Excel will automatically create a coupled PivotTable.

Excel Data Analysis — Data Validation

Data Validation is a very useful and easy to use tool in Excel with which you can set data validations on the data that is entered that is entered into your Worksheet.

For any cell on the worksheet, you can

• Display an input message on what needs to be entered into it.
• Restrict the values that get entered.
• Provide a list of values to choose from.
• Display an error message and reject an invalid data entry.

Consider the following Risk Tracker that can be used to enter and track the identified Risks information.

In this tracker, the data that is entered into the following columns is validated with preset data constraints and the entered data is accepted only when it meets the validation criteria. Otherwise, you will get an error message.

• Probability
• Impact
• Risk Category
• Risk Source
• Status

The column Risk Exposure will have calculated values and you cannot enter any data. Even the column S. No. is set to have calculated values that are adjusted even if you delete a row.

Now, you will learn how to set up such a worksheet.

Prepare the Structure for the Worksheet

To prepare the structure for the worksheet −

• Start with a blank worksheet.
• Put the header in Row 2.
• Put the column headers in Row 3.
• For the column headers Probability, Impact and Risk Exposure −

Note − It is very important to check the spelling and grammar of your messages.

Set Valid Criteria for the Risk Category Column

Now, you are ready to apply the Data Validation criteria to all the cells in the Risk Category column.

At this point, you need to remember two things −

• You need to set the criteria for maximum number of cells that are possible to be used. In our example, it can vary from 10 – 100 based on where the worksheet will be used.

• You should not set the criteria for unwanted range of cells or for the entire column. This will unnecessarily increases the file size. It is called excess formatting. If you get a worksheet from an outside source, you have to remove the excess formatting, which you will learn in the chapter on Inquire in this tutorial.

Follow the steps given below −

• Set the validation criteria for 10 cells under Risk Category.
• You can easily do this by clicking on the right-bottom corner of the first cell.
• Hold on the + symbol that appears and pull it down.

Data Validation is set for all the selected cells. Data Validation for the column Impact is complete.

Set the Column Risk Exposure with Calculated Values

Risk Exposure is calculated as a product of Risk Probability and Risk Impact.

Risk Exposure = Probability * Impact

Type =E6*F6 in cell G6 and press Enter.

0 will be displayed in the cell G6 as E6 and F6 are empty.

Copy the formula in the cells G6 – G15. 0 will be displayed in the cells G6 — G15.

As the Risk Exposure column is meant for calculated values, you should not allow data entry in that column.

• Select cells G6-G15

• Right-click and in the dropdown list that appears, select Format Cells. The Format Cells dialog box appears.

• Click the Protection tab.

• Check the option Locked.

This is to ensure that data entry is not allowed in those cells. However, this will come into effect only when the worksheet is protected, which you will do as the last step after the worksheet is ready.

• Click OK.
• Shade the cells G6-G15 to indicate they are calculated values.

Format Serial Number Values

You can leave it to the user to fill in the S. No. Column. However, if you format the S. No. values, the worksheet looks more presentable. In addition, it shows for how many rows the worksheet is formatted.

Type =row()-5 in the cell B6 and press Enter.

1 will appear in cell B6. Copy the formula in the cells B6-B15. Values 1-10 appear.

• Click OK.

Your worksheet with Data Validation set for selected cells is ready to use.

Excel Data Financial Analysis

You can perform financial analysis with Excel in an easy way. Excel provides you several financial functions such as PMT, PV, NPV, XNPV, IRR, MIRR, XIRR, and so on that enable you to quickly arrive at the financial analysis results.

In this chapter, you will learn where and how you can use these functions for your analysis.

What is Annuity?

An annuity is a series of constant cash payments made over a continuous period. For example, savings for retirement, insurance payments, home loan, mortgage, etc. In annuity functions −

• A positive number represents cash received.
• A negative number represents cash paid out.

Present Value of a series of Future Payments

The present value is the total amount that a series of future payments is worth now. You can calculate the present value using the Excel functions −

• PV − Calculates the present value of an investment by using an interest rate and a series of future payments (negative values) and income (positive values). At least one of the cash flows must be positive and at least one must be negative.

• NPV − Calculates the net present value of an investment by using a discount rate and a series of periodic future payments (negative values) and income (positive values).

• XNPV − Calculates the net present value for a schedule of cash flows that is not necessarily periodic.

Note that −

• PV cash flows must be constant whereas NPV cash flows can be variable.

• PV cash flows can be either at the beginning or at the end of the period whereas NPV cash flows must be at the end of the period.

• NPV cash flows must be periodic whereas XNPV cash flows need not be periodic.

In this section, you will understand how to work with PV. You will learn about NPV in a later section.

Example

Suppose you are buying a refrigerator. The salesperson tells you that the price of the refrigerator is 32000, but you have an option to pay out the amount in 8 years with an interest rate of 13% per annum and yearly payments of 6000. You also have an option to make the payments either at the beginning or end of each year.

You want to know which of these options is beneficial for you.

You can use Excel function PV −

PV (rate, nper, pmt, [fv ], [type])

To calculate present value with payments at the end of each year, omit type or specify 0 for type.

To calculate present value with payments at the end of each year, specify 1 for type.

You will get the following results −

Therefore,

• If you make the payment now, you need to pay 32,000 of present value.
• If you opt for yearly payments with payment at the end of the year, you need to pay 28, 793 of present value.
• If you opt for yearly payments with payment at the end of the year, you need to pay 32,536 of present value.

You can clearly see that option 2 is beneficial for you.

What is EMI?

An Equated Monthly Installment (EMI) is defined by Investopedia as «A fixed payment amount made by a borrower to a lender at a specified date each calendar month. Equated monthly installments are used to pay off both interest and principal each month, so that over a specified number of years, the loan is paid off in full.»

EMI on a Loan

In Excel, you can calculate the EMI on a loan with the PMT function.

Suppose, you want to take a home loan of 5000000 with an annual interest rate of 11.5% and the term of the loan for 25 years. You can find your EMI as follows −

• Calculate interest rate per month (Interest Rate per Annum/12)
• Calculate number of monthly payments (No. of years * 12)
• Use PMT function to calculate EMI

As you observe,

• Present Value (PV) is the loan amount.
• Future Value (FV) is 0 as at the end of the term the loan amount should be 0.
• Type is 1 as the EMIs are paid at the beginning of each month.

You will get the following results −

Monthly Payment of Principal and Interest on a Loan

EMI includes both-interest and a part payment of principal. As the time increases, these two components of EMI will vary, reducing the balance.

To get

• The interest part of your monthly payments, you can use the Excel IPMT function.

• The payment of principal part of your monthly payments, you can use the Excel PPMT function.

For example, if you have taken a loan of 1,000,000 for a term of 8 months at the rate of 16% per annum. You can get values for the EMI, the decreasing interest amounts, the increasing payment of principal amounts and the diminishing loan balance over the 8 months. At the end of 8 months, loan balance will be 0.

Follow the procedure given below.

Step 1 − Calculate the EMI as follows.

This results in an EMI of Rs. 13261.59.

Step 2 − Next calculate the interest and principal parts of the EMI for the 8 months as shown below.

You will get the following results.

Interest and Principal paid between two Periods

You can compute the interest and principal paid between two periods, inclusive.

• Compute the cumulative interest paid between 2^nd and 3^rd months using the CUMIPMT function.

• Verify the result summing up the interest values for 2^nd and 3^rd months.

• Compute the cumulative principal paid between 2^nd and 3^rd months using the CUMPRINC function.

• Verify the result summing up the principal values for 2^nd and 3^rd months.

You will get the following results.

You can see that your calculations match with your verification results.

Calculating Interest Rate

Suppose you take a loan of 100,000 and you want to pay back in 15 months with a maximum monthly payment of 12000. You might want to know the interest rate at which you have to pay.

Find the interest rate with the Excel RATE function −

You will get the result as 8%.

Calculating Term of Loan

Suppose you take a loan of 100,000 at the interest rate 10%. You want a maximum monthly payment of 15,000. You might want to know how long it will take for you to clear the loan.

Find the number of payments with Excel NPER function

You will get the result as 12 months.

Decisions on Investments

When you want to make an investment, you compare the different options and choose the one that yields better returns. Net present value is useful in comparing cash flows over a period of time and deciding which one is better. The cash flows can occur at regular, periodical intervals or at irregular intervals.

First, we consider the case of regular, periodical cash flows.

The net present value of a sequence of cash flows received at different points in time in n years from now (n can be a fraction) is 1/(1 + r)ⁿ, where r is the annual interest rate.

Consider the following two investments over a period of 3 years.

At face value, Investment 1 looks better than Investment 2. However, you can decide on which investment is better only when you know the true worth of the investment as of today. You can use the NPV function to calculate the returns.

The cash flows can occur

• At the end of every year.
• At the beginning of every year.
• In the middle of every year.

NPV function assumes that the cash flows are at the end of the year. If the cash flows occur at different times then you have to take into account that particular factor along with the calculation with NPV.

Suppose the cash flows occur at the end of the year. Then you can straight away use the NPV function.

You will get the following results −

As you observe NPV for Investment 2 is higher than that for Investment 1. Hence, Investment 2 is a better choice. You got this result as cash out flows for Investment 2 are at later periods as compared to that of Investment 1.

Cash Flows at the Beginning of the Year

Suppose the cash flows occur at the beginning of every year. In such a case, you should not include the first cash flow in NPV calculation as it already represents the current value. You need to add the first cash flow to the NPV obtained from rest of the cash flows to get the net present value.

You will get the following results −

Cash Flows in the Middle of the Year

Suppose the cash flows occur in the middle of every year. In such a case, you need to multiply the NPV obtained from the cash flows by $sqrt{1+r}$ to get the net present value.

You will get the following results −

Cash Flows at Irregular Intervals

If you want to calculate the net present value with irregular cash flows, i.e. cash flows occurring at random times, the calculation is a bit complex.

However, in Excel, you can easily do such a calculation with XNPV function.

• Arrange your data with the dates and the cash flows.

Note − The first date in your data should be the earliest of all the dates. The other dates can occur in any order.

• Use the XNPV function to calculate the net present value.

You will get the following results −

Suppose today’s date is 15^th March, 2015. As you observe, all the dates of cash flows are of later dates. If you want to find the net present value as of today, include it in the data at the top and specify 0 for the cash flow.

You will get the following results −

Internal Rate of Return (IRR)

Internal Rate of Return (IRR) of an investment is the rate of interest at which NPV is 0. It is the rate value for which the present values of the positive cash flows exactly compensate the negative ones. When the discount rate is the IRR, the investment is perfectly indifferent, i.e. the investor is neither gaining nor losing money.

Consider the following cash flows, different interest rates and the corresponding NPV values.

As you can observe between the values of interest rate 10% and 11%, the sign of NPV changes. When you fine-tune the interest rate to 10.53%, NPV is nearly 0. Hence, IRR is 10.53%.

Determining IRR of Cash Flows for a Project

You can calculate IRR of cash flows with Excel function IRR.

The IRR is 10.53% as you had seen in the previous section.

For the given cash flows, IRR may −

• exist and unique
• exist and multiple
• not exist

Unique IRR

If IRR exists and is unique, it can be used to choose the best investment among several possibilities.

• If the first cash flow is negative, it means the investor has the money and wants to invest. Then, the higher the IRR the better, since it represents the interest rate the investor is receiving.

• If the first cash flow is positive, it means the investor needs money and is looking for a loan, the lower the IRR the better since it represents the interest rate the investor is paying.

To find if an IRR is unique or not, vary the guess value and calculate IRR. If IRR remains constant then it is unique.

As you observe, the IRR has a unique value for the different guess values.

Multiple IRRs

In certain cases, you may have multiple IRRs. Consider the following cash flows. Calculate IRR with different guess values.

You will get the following results −

You can observe that there are two IRRs — -9.59% and 216.09%. You can verify these two IRRs calculating NPV.

For both -9.59% and 216.09%, NPV is 0.

No IRRs

In certain cases, you may not have IRR. Consider the following cash flows. Calculate IRR with different guess values.

You will get the result as #NUM for all the guess values.

The result #NUM means that there is no IRR for the cash flows considered.

Cash Flows Patterns and IRR

If there is only one sign change in the cash flows, such as from negative to positive or positive to negative, then a unique IRR is guaranteed. For example, in capital investments, the first cash flow will be negative, while the rest of the cash flows will be positive. In such cases, unique IRR exists.

If there is more than one sign change in the cash flows, IRR may not exist. Even if it exists, it may not be unique.

Decisions based on IRRs

Many analysts prefer to use IRR and it is a popular profitability measure because, as a percentage, it is easy to understand and easy to compare to the required return. However, there are certain problems while making decisions with IRR. If you rank with IRRs and make decisions based on these ranks, you may end up with wrong decisions.

You have already seen that NPV will enable you to make financial decisions. However, IRR and NPV will not always lead to the same decision when projects are mutually exclusive.

Mutually exclusive projects are those for which the selection of one project precludes the acceptance of another. When projects that are being compared are mutually exclusive, a ranking conflict may arise between NPV and IRR. If you have to choose between project A and project B, NPV may suggest acceptance of project A whereas IRR may suggest project B.

This type of conflict between NPV and IRR may arise because of one of the following reasons −

• The projects are of greatly different sizes, or
• The timing of the cash flows are different.

Projects of significant size difference

If you want to make a decision by IRR, project A yields a return of 100 and Project B a return of 50. Hence, investment on project A looks profitable. However, this is a wrong decision because of the difference in the scale of projects.

• You have 1000 to invest.

• If you invest entire 1000 on project A, you get a return of 100.

• If you invest 100 on project B, you will still have 900 in your hand that you can invest on another project, say project C. Suppose you get a return of 20% on project C, then the total return on project B and project C is 230, which is way ahead in profitability.

Thus, NPV is a better way for decision making in such cases.

Projects with different cash flows timings

Again, if you consider IRR to decide, project B would be the choice. However, project A has a higher NPV and is an ideal choice.

IRR of Irregularly Spaced Cash Flows (XIRR)

Your cash flows may sometimes be irregularly spaced. In such a case, you cannot use IRR as IRR requires equally spaced time intervals. You can use XIRR instead, which takes into account the dates of the cash flows along with the cash flows.

The Internal Rate of Return that results in is 26.42%.

Modified IRR (MIRR)

Consider a case when your finance rate is different from your reinvestment rate. If you calculate Internal Rate of Return with IRR, it assumes same rate for both finance and reinvestment. Further, you might also get multiple IRRs.

For example, consider the cash flows given below −

As you observe, NPV is 0 more than once, resulting in multiple IRRs. Further, reinvestment rate is not taken into account. In such cases, you can use modified IRR (MIRR).

You will get a result of 7% as shown below −

Note − Unlike IRR, MIRR will always be unique.

Working with Multiple Sheets

In certain situations, you might have to

• Set up workbooks in which several worksheets have a similar format or structure.
• Get information for these worksheets from another worksheet.
• Summarize the results from these worksheets into a summary worksheet.

For example, you might have to track sales information region wise and month wise in separate worksheets. The price of each product is taken from the product catalog that is set up across the company in a separate worksheet. Finally, you have to summarize the results across all the regions into a summary sheet.

In this chapter, you will learn how you can accomplish this in easy steps. You are going to summarize results from April 2015 to March 2016, i.e. financial year 2015-16.

The First Step

The first step is to set up a product catalog. Follow the steps given below −

• Start with a blank workbook.
• Set up product catalog worksheet with products and prices.
• Name the worksheet Product Catalog.
• Assume the catalog is revised on the first of every month.
• Provide a place holder for last updated on.

The price of a product at selling time is determined by the current cost of the product.

Multiple Worksheets with same Structure

Next, you have to set up worksheets for the Regions – East, North, South, and West, in that order with same structure.

• Add 4 blank worksheets.
• Name the worksheets East, North, South and West.

These four worksheets should have the same structure.

• Click the tab East. The East worksheet opens.
• Press the shift key and click on the tab West. All the 4 tabs will be selected.

Now, whatever editing you do in the East worksheet will get automatically reflected in the other three selected worksheets.

In the East worksheet,

• Add the column headers – S. No., Month, Product, Price, No. of Units, Total Amount.
• Add the S. No., Month April and the 4 Product Names.
• Format the Table.

The same structure appears in the other worksheets North, South and West.

Creating a Formula across Multiple Worksheets

To create a formula across multiple worksheets −

• Define names for the price values of the products in the product catalog worksheet.
• Set the Scope as Workbook for all the names.

• Once again select all the four worksheets – East, North, South and West.
• In the East worksheet, for each product, in the price column, give the formula as the Price Value Name.

As we defined earlier, the price of a product is as per the product catalog that is updated on the first of every month.

• Repeat the same steps for each Month

Therefore, for the worksheets for the regions East, North, South, and West, you have successfully set the same structure and placed the price information for each product based on the month from product catalog worksheet.

The Product Catalog can be in another Workbook too.

Calculations in the Worksheets

The next step is to fill in the information of No. of Units sold for each Product in each Month and in each Region. Therefore, you need to work separately on these worksheets.

For each region, for each product −

• Fill No. of Units sold.
• Calculate the corresponding Total Amount as Price*No. of Units.

In each worksheet (East, North, South and West), calculate subtotals month-wise −

Note − You can use Subtotal on a single worksheet but not on multiple worksheets. Hence, you have to repeat this step for North, South and West worksheets.

Click the Outline Level 2. You will get all month-wise Totals.

Now, you are ready to summarize the results from all the four worksheets – East, North, South and West.

Summarizing Data in Multiple Worksheets

The following steps will show you how to summarize data from multiple worksheets.

• Add a worksheet and name it Summary.
• Create the structure for Summary worksheet.

In the column- Total Sales, in the cell C3, type =sum(

• Select the worksheet East.
• Select the cell G7.
• With East tab pressed, click the tab West.
• The tabs East to West get selected.
• The formula in the formula bar appears as

=sum(‘East:West’!G7)

Note that you are still in the East worksheet. Press Enter.

You will be in the Summary worksheet. In the formula bar, you will see the formula as

=SUM(East:West!G7)

The calculated value appears in the cell C3.

• Copy the formula to the cells C4 to C14.
• Click Show Formulas in the Formula Auditing group under the FORMULAS tab.

All the formulas in the column Total Sales appear.

This is exactly how you wanted to summarize the results from each region.

• Click in the cell C15.
• Type =sum(C3:C14)

Your summarized results are ready in the Summary worksheet.

Excel Data Analysis — Formula Auditing

You might want to check formulas for accuracy or find the source of an error. Excel Formula Auditing commands provide you an easy way to find

• Which cells are contributing in the calculation of a formula in the active cell.
• Which formulas are referring to the active cell.

These findings are shown graphically by arrow lines that makes the visualization easy. You can display all the formulas in the active worksheet with a single command. If your formulas refer to cells in a different workbook, open that workbook also. Excel cannot go to a cell in a workbook that is not open.

Setting the Display Options

You need to check whether the display options for the workbooks you are using are correctly set.

• Click FILE > Options.
• In the Excel Options dialog box, click Advanced.
• In Display options for the workbook −
  • Select the workbook.
  • Check that under For objects, show, All is selected.
• Repeat this step for all the workbooks you are auditing.

Tracing Precedents

Precedent cells are those cells that are referred to by a formula in the active cell.

In the following example, the active cell is C2. In C2, you have the formula =B2*C4.

B2 and C4 are precedent cells for C2.

To trace the precedents of the cell C2,

• Click in the cell C2.
• Click the Formulas tab.
• Click Trace Precedents in the Formula Auditing group.

Two arrows, one from B2 to C2 and another from C4 to C2 will be displayed, tracing the precedents.

Note that for tracing precedents of a cell, the cell should have a formula with valid references. Otherwise, you will get an error message.

• Click in a cell that does not contain a formula or click in an empty cell.
• Click Trace Precedents in the Formula Auditing group.

You will get a message.

Removing Arrows

Click Remove Arrows in the Formula Auditing group.

All the arrows in the worksheet will disappear.

Tracing Dependents

Dependent cells contain formulas that refer to other cells. That means, if the active cell contributes to a formula in another cell, the other cell is a dependent cell on the active cell.

In the example below, C2 has the formula =B2*C4. Therefore, C2 is a dependent cell on the cells B2 and C4

To trace the dependents of the cell B2,

• Click in the cell B2.
• Click the Formulas tab.
• Click Trace Dependents in the Formula Auditing group.

An arrow appears from B2 to C2, showing C2 is dependent on B2.

To trace the dependents of the cell C4 −

• Click in the cell C4.
• Click the Formula tab > Trace Dependents in the Formula Auditing group.

Another arrow appears from C4 to C2, showing C2 is dependent on C4 also.

Click Remove Arrows in the Formula Auditing group. All the arrows in the worksheet will disappear.

Note − For tracing dependents of a cell, the cell should be referenced by a formula in another cell. Otherwise, you will get an error message.

• Click in the cell B6 is not referenced by any formula or click in any empty cell.
• Click Trace Dependents in the Formula Auditing group. You will get a message.

Working with Formulae

You have understood the concept of Precedents and Dependents. Now, consider a worksheet with several formulae.

• Click in a cell under Pass Category in Exam Results table.
• Click Trace Precedents. The cell to its left (Marks) and the range E4:F8 will be mapped as the precedents.
• Repeat for all the cells under Pass Category in Exam Results table.

• Click in a cell under Pass Category in Student Grades table.

• Click Trace Dependents. All the cells under Pass Category in Exam Results table will be mapped as the dependents.

Showing Formulas

The worksheet below contains the summary of sales by the salespersons in the regions East, North, South, and West.

• Click the FORMULAS tab on the Ribbon.

• Click Show Formulas in the Formula Auditing group. The Formulas in the worksheet will appear, so that you will know which cells contain formulas and what the formulas are.

• Click in a cell under TotalSales.

• Click Trace Precedents. A worksheet icon appears at the end of the arrow. The worksheet icon indicates that the precedents are in a different worksheet.

Double-click on the arrow. A Go TO dialog box appears, showing the precedents.

As you observe, there are four precedents, on four different worksheets.

• Click a reference of one of the precedents.
• The reference appears in the Reference box.
• Click OK. The worksheet containing that precedent appears.

Evaluating a Formula

To find how a complex formula in a cell works step by step, you can use Evaluate Formula command.

Consider the formula NPV (Middle Year) in the cell C14. The formula is

=SQRT (1 + C2)*C10

• Click in the cell C14.
• Click the FORMULAS tab on the Ribbon.
• Click Evaluate Formula in the Formula Auditing group. The Evaluate Formula dialog box appears.

In the Evaluate Formula dialog box, the formula is displayed in the box under Evaluation. By clicking the Evaluate button several times, the formula gets evaluated step-wise. The expression with an underline will always be executed next.

Here, C2 is underlined in the formula. So, it is evaluated in the next step. Click Evaluate.

Cell C2 has value 0.2. Hence, C2 will be evaluated as 0.2. 1+0.2 is underlined showing it as the next step. Click Evaluate.

1+0.2 will be evaluated as 1.2. SQRT(1.2) is underlined showing it as next step. Click Evaluate.

SQRT(1.2) will be evaluated as 1.09544511501033. C10 is underlined showing it as next step. Click Evaluate.

C10 will be evaluated as 4976.8518518515.

1.09544511501033*4976.8518518515 is underlined showing it as next step. Click Evaluate.

1.09544511501033*4976.8518518515 will be evaluated as 5,451.87.

There are no more expressions to evaluate and this is the answer. The Evaluate button will be changed to Restart button, indicating completion of evaluation.

Error Checking

It is a good practice to do an error check once your worksheet and/or workbook is ready with calculations.

Consider the following simple calculations.

The calculation in the cell has resulted in the error #DIV/0!.

• Click in the cell C5.

• Click the FORMULAS tab on the Ribbon.

• Click the arrow next to Error Checking in the Formula Auditing group. In the drop-down list, you will find that Circular References is deactivated, indicating that your worksheet has no circular references.

• Select Trace Error from the drop-down list.

The cells needed to compute the active cell are indicated by blue arrows.

• Click Remove Arrows.
• Click the arrow next to Error Checking.
• Select Error Checking from the drop-down list.

The Error Checking dialog box appears.

Observe the following −

• If you click Help on this error, Excel help on the error will be displayed.

• If you click Show Calculation Steps, Evaluate Formula dialog box appears.

• If you click Ignore Error, the Error Checking dialog box closes and if you click Error Checking command again, it ignores this error.

• If you click Edit in Formula Bar, you will be taken to the formula in the formula bar, so that you can edit the formula in the cell.

Advanced Data Analysis — Overview

Excel provides several commands, functions and tools that make your complex data analysis tasks easy. Excel lets you perform various complex calculations with ease. In this tutorial, you will understand the versatile data analysis tools of Excel. You will understand data analysis with relevant examples, step by step instructions and screen shots at every step.

Data Consolidation

You might have to consolidate the data from various sources and present a report. The data could be in the worksheets of the same workbook or in different workbooks. With Excel data tool Consolidate, you can perform this in a few easy steps.

What-If Analysis

What-If Analysis provides you tools to handle the following data analysis situations −

• Find the input values that result in a specified value. The result could be set up as a formula with the input values as variables. By varying the values of the input variables, Excel provides the solution with the Goal Seek Tool.

• Find the possible output values by varying the values of one or two variables. The result could be set up as a formula with one or two input values as variables. By varying the values for the input variables, Excel provides the solution with the Data Table Tool.

• Find the possible output values that are a result of varying the values of more than two variables. The result could be set up as a formula with the input values as variables. By varying the values for the input variables, Excel provides the solution with the Scenario Manager Tool.

Optimizing with Excel Solver Add-in

Solver is used to handle complex goal seek situations. In such cases, in addition to the inputs and outputs, there will be defined constraints or limits imposed on the possible input values. Further, Solver is used to result in an optimal solution.

Excel has a Solver Add-in that helps you solve such complex problems.

Importing Data into Excel

Your data analysis might depend on various external data sources. In Excel, you can import data from different data sources, such as Microsoft Access Database, Web Pages, Text Files, SQL Server Table, SQL Server Analysis Cube, XML File, etc.

You can import any number of data tables simultaneously from a database. When you are importing multiple tables from a relational database such as Access, the existing relationships among the tables will be retained in Excel also. While importing the data, you can also optionally create a PivotTable or PivotChart or Power View report based on that data.

You can just create a data connection with a data source, or import the data into Excel. If you import the data into Excel, the data tables are added to the Data Model in Excel.

Data Model

Data Model in Excel is used to integrate data from multiple tables in the current workbook and / or from the imported data and / or from the data sources connected to the workbook through data connections. Data model is used transparently in PivotTable, PivotChart, PowerPivot and Power View reports.

• You can create a Data Model while importing data, or from the Excel tables in the workbook.

• The data tables in the Data Model can be viewed either in Data View or Diagram View.

• With a Data Model, you can create relationships among the data tables.

• You can either use the Create Relationship command or just click and drag and connect the fields in the two tables that define the relationship in the diagram view of the Data Model.

Exploring Data with PivotTable

As you can integrate the Data Model with a PivotTable, you can do extensive data analysis by collating, connecting, summarizing and reporting data from several different sources. As you can import tables from external data sources and create a PivotTable, it is possible to have automatic updates of the values in the PivotTable whenever the data in the connected data sources is updated.

You can create a PivotTable with the fields from multiple tables, provided the tables have relationships defined. If a relationship does not exist, Excel prompts you to create one and you can do so from the PivotTable itself. The relationship that you so define is reflected in the Data Model.

Exploring Data with PowerPivot

You can use PowerPivot to access, analyze and report data from various data sources. PowerPivot can help you handle large data with ease and produce fascinating analysis reports.

PowerPivot provides you commands to manage the Data Model, add Excel tables to Data Model, to add calculated fields in the Data Tables, to define KPIs, etc.

Exploring Data with Power View

Power View provides interactive exploration, visualization and analysis of large data. Owing to its versatile visualization options, you can definitely find the one that gives your data the perfect platform wherein you can explore the data, summarize and report.

Ranging from Tables to Maps, it is just a play for you to visualize your data, filter it, analyze it, and report it interactively. Moreover, you can have multiple visualizations on the same Power View sheet that reflect and highlight values, when you click on a data point in any one of them.

You can explore data in Power View with a table, a matrix, a card, different chart types, multiples, maps and tiles. You will get fascinated with the versatility of these different views once you get hands-on experience. This is because it is easy to produce interactive reports highlighting significant values and dynamically switching across the views.

Exploring Data with Hierarchies

If your data has hierarchies, they can be either defined in the Data Model that is reflected in the Power View or build the hierarchies in Power View itself.

Once a hierarchy is defined, you can drill-up and drill-down the hierarchy, displaying the required data.

Aesthetic Power View Reports

You can arrive at a report layout based on what you want to present in Power View. You can add a background image that reflects your company logo or your corporate view. Optionally, you can format the background of the report to give it an elegant look.

You can select a theme for your report that best portrays your data. You can change the font and text size so that your report becomes easily readable.

Key Performance Indicators (KPIs)

Key Performance Indicators are commonly used to gauge the performance. In Excel, you define and portray KPIs in PowerPivot or Power View. The graphical presentation of KPIs will uplift your reports.

Advanced Data Analysis — Data Consolidation

You might have come across different situations wherein you have to present consolidated data. The source of the data could be from one place, or several places. Another challenge could be that the data might be updated by other people from time to time.

You need to know how you can set up a summary worksheet that consolidates the data from the sources that you set up, whenever you want. In Excel, you can easily perform this task in a few steps with the Data Tool – Consolidate.

Preparing Data for Consolidation

Before you begin consolidating the data, make sure that there is consistency across the data sources. This means that the data is arranged as follows −

• Each range of data is on a separate worksheet.

• Each range of data is in list format, with labels in the first row.

• Additionally, you can have labels for the categories, if applicable, in the first column.

• All the ranges of data have the same layout.

• All the ranges of data contain similar facts.

• There are no blank rows or columns within each range.

In case the data sources are external, ensure usage of a predefined layout in the form of an Excel template.

Suppose you have the sales data of various commodities from each of the regions – East, North, South, and West. You might need to consolidate this data and present a product wise summary of sales from time to time. Preparation includes the following −

• One worksheet per region – i.e. four worksheets with names East, North, South, and West. These could be in the same workbook or different workbooks.

• Each worksheet has same layout, representing the details of product, number of units, and amount.

• You need to consolidate the data product wise. Hence, ensure that the column with the label Product is the first column and it contains the Product labels.

Consolidating Data in the Same Workbook

If you have all the data, that you have to consolidate, in the same workbook, proceed as follows −

Step 1 − Ensure that data of each region is on a separate worksheet.

Step 2 − Add a new worksheet and name it Summary.

Step 3 − Click the Summary worksheet.

Step 4 − Click the cell where you want to place the summary results.

Step 5 − Click the DATA tab on the Ribbon.

Step 6 − Click the Consolidate button in the Data Tools group.

The Consolidate dialog box appears.

Step 7 − Select Sum from the dropdown list under Function.

Step 8 − Select the data from each worksheet as follows.

• Click the icon in the box under Reference.
• Select the worksheet – East.
• Select the data range.
• Again, click the icon in the box under Reference.

The selected range appears in the Reference box −

Step 9 − Click the Add button to the right of the box. The selected data range appears in the box under All References.

Step 10 − Repeat Steps 1-5 for the rest of the data worksheets – North, South, and West. The Consolidate dialog box looks as follows.

You can see that the data ranges appear worksheet wise in alphabetical order, in the box under All references.

Step 11 − Check the boxes Top row and Left column under Use labels in. Click OK.

Your data is summarized product wise for the regions – East, North, South and West.

You can repeat the steps given above to refresh your summary results manually, whenever you need them.

Consolidating Data Automatically

Suppose you want your summary sheet to be updated automatically, whenever there are changes in the data. To accomplish this, you need to have links to the source data.

Step 1 − Check the box — Create links to source data in the Consolidate dialog box and click OK.

Your summary results appear with an outline as follows −

You will observe that a new column is inserted to the right of the column named Product.

Step 2 − Click the + sign on the outline in the row containing the Product value named Soap. You can see that the new column contains the consolidated value for each set of product values, region wise.

Consolidating Data from Different Workbooks

In the previous example, all the data that you need to summarize is in the same workbook. However, it is likely that the data is maintained separately for each region and is updated region wise. In such a case, you can consolidate the data as follows −

Step 1 − Open the workbooks containing the data, say, workbooks – East-Sales, North-Sales, South-Sales and West-Sales.

Step 2 − Open a new workbook.

Step 3 − On a new worksheet, click a cell where you want the summary to appear.

Step 4 − Click the DATA tab on the Ribbon.

Step 5 − Click Consolidate in the Data Tools box.

A Consolidate dialog box appears. In the Consolidate dialog box −

• Select Sum from the dropdown list in the box under Function.
• Click the icon in the box under Reference.
• Select the workbook – East-Sales.xlsx.
• Select the data range.
• Again, click the icon in the box under Reference.
• Click the Add button to the right.

The Consolidate dialog box looks as follows −

• Click the icon to the right of the box under References.
• Select the workbook – North-Sales.xlsx.
• Select the data range.
• Again, click the icon to the right of the box under References.
• Click Add.

Step 6 − Repeat the steps 1–6 to add the data ranges from the workbooks – South-Sales.xlsx and West-Sales.xlsx.

Step 7 − Under Use labels in, check the following boxes.

• Top row.
• Left column.

Step 8 − Check the box Create links to source data.

Your Consolidate dialog box looks as follows −

Your data is summarized in your workbook.

Advanced Data Analysis — What-If Analysis

What-if analysis is the process of changing the values in cells to see how those changes will affect the outcome of formulas on the worksheet. You can use several different sets of values in one or more formulas to explore all the various results.

What-if analysis is useful in many situations while doing data analysis. For example −

• You can propose different budgets based on revenue.

• You can predict the future values based on the given historical values.

• If you are expecting a certain value as the result from a formula, you can find different sets of input values that produce the desired result.

Excel provides you with the following What-if analysis tools that can be used based on your data analysis needs −

• Data Tables
• Scenario Manager
• Goal Seek

Data Tables and Scenarios take sets of input values and project forward to determine possible results. Goal seek differs from Data Tables and Scenarios in that it takes a result and projects backwards to determine possible input values that produce that result.

In this chapter, you will understand the possible situations where you can use the Whatif Analysis tools. For details on usage of these tools, refer to the later chapters in this tutorial.

Data Tables

A Data Table is a range of cells in which you can change values in some of the cells and come up with different answers to a problem. For example, you might want to know how much loan you can afford for a home by analyzing different loan amounts and interest rates. You can put these different values along with the PMT function in a Data Table and get the desired result.

A Data Table works only with one or two variables, but it can accept many different values for those variables.

For the details on Data Tables, refer to the chapter – What-If Analysis with Data Tables in this tutorial.

Scenario Manager

A scenario is a set of values that Excel saves and can substitute automatically in cells on a worksheet.

The key features are −

• You can create and save different groups of values on a worksheet and then switch to any of these new scenarios to view different results.

• A scenario can have multiple variables, but it can accommodate only up to 32 values.

• You can also create a scenario summary report, which combines all the scenarios on one worksheet. For example, you can create several different budget scenarios that compare various possible income levels and expenses, and then create a report that lets you compare the scenarios side-by-side.

• Scenario Manager is a dialog box that allows you to save the values as a scenario and name the scenario.

For the details on Scenarios, refer to the chapter – What-If Analysis with Scenario Manager in this tutorial.

Goal Seek

Goal Seek is useful if you know the result that you want from a formula, but not sure what input value the formula needs, to get that result. For example, if you want to borrow a loan and you know the loan amount, tenure of loan and the EMI that you can pay, you can use Goal Seek to find the interest rate at which you can avail the loan.

Goal Seek can be used only with one variable input value. If you have more than one variable for input values, you can use the Solver add-in.

For details on the usage of Goal Seek, refer to the chapter – What-If Analysis with Goal Seek in this tutorial.

Solver

Solver comes with Excel as an add-in. You can use Solver to find an optimal value for a formula in a cell called the target cell on a worksheet.

Solver works with a group of cells that are related to the formula in the target cell. Solver adjusts the values in the adjustable cells that you specify, to produce the result that you specify, from the target cell formula.

For the details on the usage of Excel Solver add-in, refer to the chapter — Optimization with Excel Solver in this tutorial.

What-If Analysis with Data Tables

With a Data Table in Excel, you can easily vary one or two inputs and perform What-if analysis. A Data Table is a range of cells in which you can change values in some of the cells and come up with different answers to a problem.

There are two types of Data Tables −

• One-variable Data Tables
• Two-variable Data Tables

If you have more than two variables in your analysis problem, you need to use Scenario Manager Tool of Excel. For details, refer to the chapter – What-If Analysis with Scenario Manager in this tutorial.

One-variable Data Tables

A one-variable Data Table can be used if you want to see how different values of one variable in one or more formulas will change the results of those formulas. In other words, with a one-variable Data Table, you can determine how changing one input changes any number of outputs. You will understand this with the help of an example.

Example

There is a loan of 5,000,000 for a tenure of 30 years. You want to know the monthly payments (EMI) for varied interest rates. You also might be interested in knowing the amount of interest and Principal that is paid in the second year.

Analysis with One-variable Data Table

Analysis with one-variable Data Table needs to be done in three steps −

Step 1 − Set the required background.

Step 2 − Create the Data Table.

Step 3 − Perform the Analysis.

Let us understand these steps in detail −

Step 1: Set the required background

• Assume that the interest rate is 12%.

• List all the required values.

• Name the cells containing the values, so that the formulas will have names instead of cell references.

• Set the calculations for EMI, Cumulative Interest and Cumulative Principal with the Excel functions – PMT, CUMIPMT and CUMPRINC respectively.

Your worksheet should look as follows −

You can see that the cells in column C are named as given in the corresponding cells in column D.

Step 2: Create the Data Table

• Type the list of values i.e. interest rates that you want to substitute in the input cell down the column E as follows −

As you observe, there is an empty row above the Interest Rate values. This row is for the formulas that you want to use.

• Type the first function (PMT) in the cell one row above and one cell to the right of the column of values. Type the other functions (CUMIPMT and CUMPRINC) in the cells to the right of the first function.

  Now, the two rows above the Interest Rate values look as follows −

The Data Table looks as given below −

Step 3: Do the analysis with the What-If Analysis Data Table Tool

• Select the range of cells that contains the formulas and values that you want to substitute, i.e. select the range – E2:H13.

• Click the DATA tab on the Ribbon.

• Click What-if Analysis in the Data Tools group.

• Select Data Table in the dropdown list.

Data Table dialog box appears.

• Click the icon in the Column input cell box.
• Click the cell Interest_Rate, which is C2.

You can see that the Column input cell is taken as $C$2. Click OK.

The Data Table is filled with the calculated results for each of the input values as shown below −

If you can pay an EMI of 54,000, you can observe that the interest rate of 12.6% is suitable for you.

Two-variable Data Tables

A two-variable Data Table can be used if you want to see how different values of two variables in a formula will change the results of that formula. In other words, with a twovariable Data Table, you can determine how changing two inputs changes a single output. You will understand this with the help of an example.

Example

There is a loan of 50,000,000. You want to know how different combinations of interest rates and loan tenures will affect the monthly payment (EMI).

Analysis with Two-variable Data Table

Analysis with two-variable Data Table needs to be done in three steps −

Step 1 − Set the required background.

Step 2 − Create the Data Table.

Step 3 − Perform the Analysis.

Step 1: Set the required background

• Assume that the interest rate is 12%.

• List all the required values.

• Name the cells containing the values, so that the formula will have names instead of cell references.

• Set the calculation for EMI with the Excel function – PMT.

Your worksheet should look as follows −

You can see that the cells in the column C are named as given in the corresponding cells in the column D.

Step 2: Create the Data Table

• Type =EMI in cell F2.

• Type the first list of input values, i.e. interest rates down the column F, starting with the cell below the formula, i.e. F3.

• Type the second list of input values, i.e. number of payments across row 2, starting with the cell to the right of the formula, i.e. G2.

  The Data Table looks as follows −

Do the analysis with the What-If Analysis Tool Data Table

• Select the range of cells that contains the formula and the two sets of values that you want to substitute, i.e. select the range – F2:L13.

• Click the DATA tab on the Ribbon.

• Click What-if Analysis in the Data Tools group.

• Select Data Table from the dropdown list.

Data Table dialog box appears.

• Click the icon in the Row input cell box.
• Click the cell NPER, which is C3.
• Again, click the icon in the Row input cell box.
• Next, click the icon in the Column input cell box.
• Click the cell Interest_Rate, which is C2.
• Again, click the icon in the Column input cell box.

You will see that the Row input cell is taken as $C$3 and the Column input cell is taken as $C$2. Click OK.

The Data Table gets filled with the calculated results for each combination of the two input values −

If you can pay an EMI of 54,000, the interest rate of 12.2% and 288 EMIs are suitable for you. This means the tenure of the loan would be 24 years.

Data Table Calculations

Data Tables are recalculated each time the worksheet containing them is recalculated, even if they have not changed. To speed up the calculations in a worksheet that contains a Data Table, you need to change the calculation options to Automatically Recalculate the worksheet but not the Data Tables, as given in the next section.

Speeding up the Calculations in a Worksheet

You can speed up the calculations in a worksheet containing Data Tables in two ways −

• From Excel Options.
• From the Ribbon.

From Excel Options

• Click the FILE tab on the Ribbon.
• Select Options from the list in the left pane.

Excel Options dialog box appears.

• From the left pane, select Formulas.

• Select the option Automatic except for data tables under Workbook Calculation in the Calculation options section. Click OK.

From the Ribbon

• Click the FORMULAS tab on the Ribbon.

• Click the Calculation Options in the Calculations group.

• Select Automatic Except for Data Tables in the dropdown list.

What-If Analysis with Scenario Manager

Scenario Manager is useful in the cases where you have more than two variables in sensitivity analysis. Scenario Manager creates scenarios for each set of the input values for the variables under consideration. Scenarios help you to explore a set of possible outcomes, supporting the following −

• Varying as many as 32 input sets.
• Merging the scenarios from several different worksheets or workbooks.

If you want to analyze more than 32 input sets, and the values represent only one or two variables, you can use Data Tables. Although it is limited to only one or two variables, a Data Table can include as many different input values as you want. Refer to What-If Analysis with Data Tables in this tutorial.

Scenarios

A scenario is a set of values that Excel saves and can substitute automatically on your worksheet. You can create and save different groups of values as scenarios on a worksheet and then switch between these scenarios to view the different results.

For example, you can have several different budget scenarios that compare various possible income levels and expenses. You can also have different loan scenarios from different sources that compare various possible interest rates and loan tenures.

If the information that you want to use in scenarios is from different sources, you can collect the information in separate workbooks, and then merge the scenarios from the different workbooks into one.

After you have all the scenarios you need, you can create a scenario summary report −

• That incorporates information from all the scenarios.
• That lets you compare the scenarios side-by-side.

Scenario Manager

Scenario Manager is one of the What-if Analysis tools in Excel.

To create an analysis report with Scenario Manager, you have to follow these steps −

Step 1 − Define the set of initial values and identify the input cells that you want to vary, called the changing cells.

Step 2 − Create each scenario, name the scenario and enter the value for each changing input cell for that scenario.

Step 3 − Select the output cells, called the result cells that you want to track. These cells contain formulas in the initial set of values. The formulas use the changing input cells.

The Scenario Manager creates a report containing the input and the output values for each scenario.

Initial Values for Scenarios

Before you create several different scenarios, you need to define a set of initial values on which the scenarios will be based.

The steps for setting up the initial values for Scenarios are −

• Define the cells that contain the input values.
• Name the input cells appropriately.
• Identify the input cells with constant values.
• Specify the values for the constant inputs.
• Identify the input cells with changing values.
• Specify the initial values for the changing inputs.
• Define the cells that contain the results. The result cells contain formulas.
• Name the result cells appropriately.
• Place the formulas in the result cells.

Consider the previous example of loan. Now, proceed as follows −

• Define a cell for Loan Amount.

  • This input value is constant for all the scenarios.

  • Name the cell Loan_Amount.

  • Specify the value as 5,000,000.

• Define the cells for Interest Rate, No. of payments and Type (Payment at the beginning or end of the month).

  • These input values will be changing across the scenarios.

  • Name the cells Interest_Rate, NPER and Type.

  • Specify the initial values for the analysis in these cells as 12%, 360 and 0 respectively.

• Define the cell for the EMI.

  • This is the result value.

  • Name the cell EMI.

  • Place the formula in this cell as −

    =PMT (Interest_Rate/12, NPER, Loan_Amount, 0, Type)

Your worksheet looks as shown below −

As you can see that the input cells and the result cells are in column C with the names as given in column D.

Creating Scenarios

After setting up the initial values for the Scenarios, you can create the scenarios using Scenario Manager as follows −

• Click the DATA tab on the Ribbon.
• Click What-if Analysis in the Data Tools group.
• Select Scenario Manager from the dropdown list.

The Scenario Manager Dialog box appears. You can observe that it contains a message −

“No Scenarios defined. Choose Add to.”

You need to create scenarios for each set of changing values in the Scenario Manager. It is good to have the first scenario defined with initial values, as it enables you to switch back to initial values whenever you want while displaying different scenarios.

Create the first scenario with the initial values as follows −

• Click the Add button in the Scenario Manager Dialog box.

The Add Scenario dialog box appears.

• Under Scenario Name, type Scenario 1.
• Under Changing Cells, enter the references for the cells i.e. C3, C4 and C5 with the Ctrl key pressed.

The name of the dialog box changes to Edit Scenario.

• Edit the text in the Comment as – Initial Values box.

• Select the option Prevent changes under Protection and then click OK.

The Scenario Values dialog box appears. The initial values that you have defined appear in each of the changing cells boxes.

Scenario 1 with the initial values is created.

Create three more scenarios with varying values in the changing cells as follows −

• Click the Add button in the Scenario Values dialog box.

Add Scenario dialog box appears. Note that C3, C4, C5 appear in the Changing cells box.

• In the Scenario Name box, type Scenario 2.

• Edit the text in the Comment as – Different Interest Rate.

• Select Prevent changes under Protection and click OK.

• In the Scenario Name box, type Scenario 3.

• Edit the text in the Comment box as – Different no. of Payments.

• Select Prevent changes under Protection and click OK.

The Scenario Values dialog box appears. The initial values appear in the changing cells. Change the value of NPER to 300 and click Add.

The Add Scenario dialog box appears. Note that C3, C4, C5 appear in the Changing cells box.

• In the Scenario Name box, type Scenario 4.

• Edit the text in the Comment box as – Different Type of Payment.

• Select Prevent changes under Protection and click OK.

The Scenario Values dialog box appears. The initial values appear in the changing cells. Change the value of Type to 1. Click OK as you have added all the scenarios that you wanted to add.

The Scenario Manager dialog box appears. In the box under Scenarios, You will find the names of all the scenarios that you have created.

• Click Scenario 1. As you are aware, Scenario 1 contains the initial values.



Now, click Summary. The Scenario Summary dialog box appears.

Scenario Summary Reports

Excel provides two types of Scenario Summary reports −

• Scenario summary.
• Scenario PivotTable report.

In the Scenario Summary dialog box, you can find these two Report types.

Select Scenario summary under Report type.

Scenario Summary

In the Result cells box, select the cell C6 (Here, we had put the PMT function). Click OK.

Scenario Summary report appears in a new worksheet. The worksheet is named as Scenario Summary.

You can observe the following in the Scenario Summary report −

• Changing Cells − Enlists all the cells used as changing cells. As you have named the cells, Interest_Rate, NPER and Type, these appear to make the report meaningful. Otherwise, only cell references will be listed.

• Result Cells − Displays the result cell specified, i.e. EMI.

• Current Values − It is the first column and enlists the values of that scenario which is selected in the Scenario Manager Dialog box before creating the summary report.

• For all the scenarios you have created, the changing cells will be highlighted in gray.

• In the EMI row, the result values for each scenario will be displayed.

You can make the report more meaningful by displaying the comments that you added while creating the scenarios.

• Click the + button to the left of the row containing the scenario names. The comments for the scenarios appear in the row under the scenario names.

Scenarios from Different Sources

Suppose you get the scenarios from three different sources and you need to prepare the Scenario summary report in a Master workbook. You can do this by merging the scenarios from different workbooks into the Master workbook. Follow the steps given below −

• Assume that the scenarios are in the workbooks, Bank1_Scenarios, Bank2_Scenarios and Bank3_Scenarios. Open the three workbooks.

• Open the Master workbook, in which you have the initial values.

• Click DATA > What-if Analysis > Scenario Manager in the Master workbook.

The Scenario Manager Dialog box appears.

As you can observe, there are no scenarios as you have not yet added any. Click Merge.

The Merge Scenarios dialog box appears.

As you can see, under Merge scenarios from, you have two boxes −

• Book
• Sheet

You can select specific worksheet from a specific workbook that contains the scenarios, which you want to add to your results. Click the drop-down arrow of Book to see the workbooks.

Note − The corresponding workbooks should be open to appear in this list.

Select the book – Bank1_Scenarios.

Bank1 sheet is displayed. At the bottom of the dialog box, the number of scenarios found on source sheet is displayed. Click OK.

The Scenario Manager dialog box appears. The two scenarios that were merged into the Master workbook will be listed under Scenarios.

Click the Merge button. The Merge Scenarios dialog box appears. Now, select Bank2_Scenarios from the drop-down list in the Book box.

Bank2 sheet is dislayed. At the bottom of the dialog box, the number of scenarios found on source sheet are displayed. Click OK.

The Scenario Manager Dialog box appears. The four scenarios that were merged into the Master workbook are listed under Scenarios.

Click the Merge button. The Merge Scenarios dialog box appears. Now, select Bank3_Scenarios from the drop-down list in the Book box.

Bank3 sheet is displayed. At the bottom of the dialog box, the number of scenarios found on source sheet will be displayed. Click OK.

The Scenario Manager Dialog box appears. The five scenarios that were merged into the Master workbook will be listed under Scenarios.

Now, you have all the required scenarios to produce the Scenario summary report.

Click the Summary button. The Scenario Summary dialog box appears.

• Select Scenario summary.
• In the Result cells box, type C6 and click OK.

The Scenario summary report appears on a new worksheet in the Master workbook.

What-If Analysis with Goal Seek

Goal Seek is a What-If Analysis tool that helps you to find the input value that results in a target value that you want. Goal Seek requires a formula that uses the input value to give result in the target value. Then, by varying the input value in the formula, Goal Seek tries to arrive at a solution for the input value.

Goal Seek works only with one variable input value. If you have more than one input value to be determined, you have to use the Solver add-in. Refer to the chapter – Optimization with Excel Solver in this tutorial.

Analysis with Goal Seek

Suppose you want to take a loan of 5,000,000 and you want to repay in 25 years. You can pay an EMI of 50000. You want to know at what interest rate you can borrow the loan.

You can use Goal Seek to find the interest rate at which you can borrow the loan as follows −

Step 1 − Set up the Excel cells for Goal Seek as given below.

Step 2 − Enter the values in column C corresponding to column D. The cell Interest_Rate is kept empty, as you have to retrieve that value. Further, though you know the EMI that you can pay (50000), that value is not included as you have to use the Excel PMT function to arrive at it. Goal Seek requires a formula to find the result. The PMT function is placed in the cell EMI so that it can be used by Goal Seek.

Excel computes the EMI with the PMT function. The table now looks like −

As the Interest_Rate cell is empty, Excel takes that value as 0 and calculates the EMI. You can ignore the result -13,888.89.

Perform the Analysis with Goal Seek as follows −

Step 1 − Go to DATA > What If Analysis > Goal Seek on the Ribbon.

The Goal Seek dialog box appears.

Step 2 − Type EMI in the Set cell box. This box is the reference for the cell that contains the formula that you want to resolve, in this case the PMT function. It is the cell C6, which you named as EMI.

Step 3 − Type -50000 in the To value box. Here, you get the formula result, in this case, the EMI that you want to pay. The number is negative because it represents a payment.

Step 4 − Type Interest_Rate in the By changing cell box. This box has the reference of the cell that contains the value you want to adjust, in this case the interest rate. It is cell C2, which you named as Interest_Rate.

Step 5 − This cell that Goal Seek changes, must be referenced by the formula in the cell that you specified in the Set cell box. Click OK.

Goal Seek produces a result, as shown below −

As you can observe, Goal Seek found the solution using cell C6 (containing the formula) as 12% that is displayed in the cell C2, which is the interest rate. Click OK.

Solving Story Problems

You can solve story problems easily with Goal Seek. Let us understand this with the help of an example.

Example

Suppose there is a bookstore that has 100 books in storage. The original price of the book is 250 and certain number of books was sold at that price. Later, the bookstore announced a 10% discount on that book and cleared off the stock. You might want to know how many books are sold at the original price to obtain a total revenue of 24,500.

You can use Goal Seek to find the solution. Follow the steps given below −

Step 1 − Set the worksheet as given below.

Step 2 − Go to DATA > What If Analysis > Goal Seek on the Ribbon.

The Goal Seek dialog box appears.

Step 3 − Type Revenue, 24500 and Books_OriginalPrice in the Set cell box, To Value box and By changing cell box respectively. Click OK.

Goal Seek displays the status and solution.

If 80 books were sold at the original price, the revenue would be 24500.

Performing a Break-even Analysis

In economy, break-even point is the point at which there is neither profit nor loss. This would mean −

Revenue = Expenses, or

Revenue – Expenses = 0

You can do break-even analysis with Goal Seek in Excel.

Example

Suppose there is a store that sells toys. You might want to make a break-even analysis of the store. Collect the following information from the store −

• Fixed cost of the store.
• Unit cost of the toy.
• Number of toys to be sold.

You need to find at which price they should sell the toys to break even.

Step 1 − Set the worksheet as given below.

Step 2 − Go to DATA > What If Analysis > Goal Seek on the Ribbon. The Goal Seek dialog box appears.

Step 3 − Type Break_even_Point, 0, and Unit_Price in the Set cell box, To value box and By changing cell box respectively. Click OK.

As you can observe, Goal Seek gave the result that if the Unit Price is 35, the store will break even.

Optimization with Excel Solver

Solver is a Microsoft Excel add-in program you can use for optimization in what-if analysis.

According to O’Brien and Marakas, optimization analysis is a more complex extension of goal-seeking analysis. Instead of setting a specific target value for a variable, the goal is to find the optimum value for one or more target variables, under certain constraints. Then, one or more other variables are changed repeatedly, subject to the specified constraints, until you discover the best values for the target variables.

In Excel, you can use Solver to find an optimal value (maximum or minimum, or a certain value) for a formula in one cell called the objective cell, subject to certain constraints or limits, on the values of other formula cells on the worksheet.

This means that the Solver works with a group of cells called decision variables that are used in computing the formulas in the objective and constraint cells. Solver adjusts the values in the decision variable cells to satisfy the limits on constraint cells and produce the result you want for the objective cell.

You can use Solver to find optimal solutions for diverse problems such as −

• Determining the monthly product mix for a drug manufacturing unit that maximizes the profitability.

• Scheduling workforce in an organization.

• Solving transportation problems.

• Financial planning and budgeting.

Activating Solver Add-in

Before you proceed with finding solution for a problem with Solver, ensure that the Solver Add-in is activated in Excel as follows −

• Click the DATA tab on the Ribbon. The Solver command should appear in the Analysis group as shown below.

In case you do not find the Solver command, activate it as follows −

• Click the FILE tab.
• Click Options in the left pane. Excel Options dialog box appears.
• Click Add-Ins in the left pane.
• Select Excel Add-Ins in the Manage box and click Go.

The Add-Ins dialog box appears. Check Solver Add-in and click Ok. Now, you should be able to find the Solver command on the Ribbon under the DATA tab.

Solving Methods used by Solver

You can choose one of the following three solving methods that Excel Solver supports, based on the type of problem −

LP Simplex

Used for linear problems. A Solver model is linear under the following conditions −

• The target cell is computed by adding together the terms of the (changing cell)*(constant) form.

• Each constraint satisfies the linear model requirement. This means that each constraint is evaluated by adding together the terms of the (changing cell)*(constant) form and comparing the sums to a constant.

Generalized Reduced Gradient (GRG) Nonlinear

Used for smooth nonlinear problems. If your target cell, any of your constraints, or both contain references to changing cells that are not of the (changing cell)*(constant) form, you have a nonlinear model.

Evolutionary

Used for smooth nonlinear problems. If your target cell, any of your constraints, or both contain references to changing cells that are not of the (changing cell)*(constant) form, you have a nonlinear model.

Understanding Solver Evaluation

The Solver requires the following parameters −

• Decision Variable Cells
• Constraint Cells
• Objective Cells
• Solving Method

Solver evaluation is based on the following −

• The values in the decision variable cells are restricted by the values in the constraint cells.

• The calculation of the value in the objective cell includes the values in the decision variable cells.

• Solver uses the chosen Solving Method to result in the optimal value in the objective cell.

Defining a Problem

Suppose you are analyzing the profits made by a company that manufactures and sells a certain product. You are asked to find the amount that can be spent on advertising in the next two quarters subject to a maximum of 20,000. The level of advertising in each quarter affects the following −

• The number of units sold, indirectly determining the amount of sales revenue.
• The associated expenses, and
• The profit.

You can proceed to define the problem as −

• Find Unit Cost.
• Find the advertising cost per Unit.
• Find Unit Price.

Next, set the cells for the required calculations as given below.

As you can observe, the calculations are done for Quarter1 and Quarter2 that are in consideration are −

• No. of units available for sale in Quarter1 is 400 and in Quarter2 is 600 (cells – C7 and D7).

• The initial values for advertising budget are set as 10000 per Quarter (Cells – C8 and D8).

• No. of units sold is dependent on the advertising cost per unit and hence is budget for the quarter / Adv. Cost per unit. Note that we have used the Min function to take care to see that the no. of units sold in <= no. of units available. (Cells – C9 and D9).

• Revenue is calculated as Unit Price * No. of Units sold (Cells – C10 and D10).

• Expenses is calculated as Unit Cost * No. of Units Available + Adv. Cost for that quarter (Cells – C11 and D12).

• Profit is Revenue – Expenses (Cells C12 and D12).

• Total Profit is Profit in Quarter1 + Profit in Quarter2 (Cell – D3).

Next, you can set the parameters for Solver as given below −

As you can observe, the parameters for Solver are −

• Objective cell is D3 that contains Total Profit, which you want to maximize.

• Decision Variable cells are C8 and D8 that contain the budgets for the two quarters – Quarter1 and Quarter2.

• There are three Constraint cells — C14, C15 and C16.

  • Cell C14 that contains total budget is to set the constraint of 20000 (cell D14).

  • Cell C15 that contains the no. of units sold in Quarter1 is to set the constraint of <= no. of units available in Quarter1 (cell D15).

  • Cell C16 that contains the no. of units sold in Quarter2 is to set the constraint of <= no. of units available in Quarter2 (cell D16).

Solving the Problem

The next step is to use Solver to find the solution as follows −

Step 1 − Go to DATA > Analysis > Solver on the Ribbon. The Solver Parameters dialog box appears.

Step 2 − In the Set Objective box, select the cell D3.

Step 3 − Select Max.

Step 4 − Select range C8:D8 in the By Changing Variable Cells box.

Step 5 − Next, click the Add button to add the three constraints that you have identified.

Step 6 − The Add Constraint dialog box appears. Set the constraint for total budget as given below and click Add.

Step 7 − Set the constraint for total no. of units sold in Quarter1 as given below and click Add.

Step 8 − Set the constraint for total no. of units sold in Quarter2 as given below and click OK.

The Solver Parameters dialog box appears with the three constraints added in box –Subject to the Constraints.

Step 9 − In the Select a Solving Method box, select Simplex LP.

Step 10 − Click the Solve button. The Solver Results dialog box appears. Select Keep Solver Solution and click OK.

The results will appear in your worksheet.

As you can observe, the optimal solution that produces maximum total profit, subject to the given constraints, is found to be the following −

• Total Profit – 30000.
• Adv. Budget for Quarter1 – 8000.
• Adv. Budget for Quarter2 – 12000.

Stepping through Solver Trial Solutions

You can step through the Solver trial solutions, looking at the iteration results.

Step 1 − Click the Options button in the Solver Parameters dialog box.

The Options dialog box appears.

Step 2 − Select the Show Iteration Results box and click OK.

Step 3 − The Solver Parameters dialog box appears. Click Solve.

Step 4 − The Show Trial Solution dialog box appears, displaying the message — Solver paused, current solution values displayed on worksheet.

As you can observe, the current iteration values are displayed in your working cells. You can either stop the Solver accepting the current results or continue with the Solver from finding solution in further steps.

Step 5 − Click Continue.

The Show Trial Solution dialog box appears at every step and finally after the optimal solution is found, Solver Results dialog box appears. Your worksheet is updated at every step, finally showing the result values.

With a Data Model, you can create relationships among the tables. Data model is used transparently in PivotTable, PivotChart, PowerPivot and Power View reports.

Creating Data Model while Importing Data

When you import data from relational databases like Microsoft Access database that contain multiple related tables, Data Model is automatically created if you import more than one table at once.

You can optionally add tables to the Data Model, when you import data from the following data sources −

• Relational databases, one table at a time
• Text Files
• Excel Workbooks

For example, while you are importing data from an Excel workbook, you can observe the option Add this data to the Data Model, with an enabled check box.

If you want to add the data you are importing to the Data Model, check the box.

Creating Data Model from Excel Tables

You can create the Data Model from Excel tables using PowerPivot commands. You will learn PowerPivot in detail in later chapters.

All the Data Model commands are available under the PowerPivot tab on the Ribbon. You can add Excel tables to the Data Model with these commands.

Consider the following sales data workbook, wherein you have Product Catalog worksheet that contains Product, Product ID and Price. You have four worksheets for the sales in 4 regions – East, North, South and West.

Each of these four worksheets contain No. of Units sold and Total Amount for each of the Products in each month. You need to calculate the total amount for each of the products in each region and total amount of sales in each region.

The following steps enable you to arrive at the desired results −

Add new rows of data to the existing tables in the Data Model.

Refresh the Data Connection. New rows of data from the data source get added to the Data Model.

Exploring Data with PivotTables

You can do extensive data analysis using PivotTables and produce desired reports. The integration of Data Model with PivotTable enhances the way the data is collated, connected, summarized and reported. You can import tables from external data sources and create a PivotTable with the imported tables. This facilitates automatic updations of the values in the PivotTable whenever the data in the connected data sources is updated.

Creating a PivotTable to analyze External Data

To create a PivotTable to analyze external data −

• Open a new blank workbook in Excel.
• Click the DATA tab on the Ribbon.
• Click From Access in the Get External Data group. The Select Data Source dialog box appears.
• Select the Access database file.

• Check the box Enable selection of multiple tables.

• Select all the tables. Click OK.

The Import Data dialog box appears. Select PivotTable Report. This option imports the tables into your Excel workbook and creates a PivotTable for analyzing the imported tables.

As you observe, the checkbox Add this data to the Data Model is selected and disabled, indicating that the tables will be added to the Data Model automatically.

The data will be imported and an empty PivotTable will be created. The imported tables appear in the PivotTable Fields list.

Exploring Data in Multiple Tables

You can analyze the data from the imported multiple tables with PivotTable and arrive at the specific report you want in just few steps. This is possible because of the pre-existing relationships among the tables in the source database. As you imported all the tables from the database together at the same time, Excel recreates the relationships in its Data Model.

In the PivotTable Fields list, you will find all the tables that you imported and the fields in each of them. If the fields are not visible for any table,

• Click on the arrow next to that table in the PivotTable Fields list.
• The fields in that table will be displayed.

Exploring Data using PivotTable

You know how to add fields to PivotTable and drag fields across areas. Even if you are not sure of the final report that you want, you can play with the data and choose the appropriate report.

Suppose you want to have a report displaying the following −

• Data for five disciplines — Archery, Diving, Fencing, Figure Skating and Speed Skating.
• Regions that scored more than 80 medals in these 5 disciplines.
• The count of medals in each of the five disciplines in each of these regions.
• Total count of medals for the five disciplines in each of these regions.

You can see how easily you can create this report in few steps.

To start with, create a PivotTable displaying the count of medals in all the regions for the selected five disciplines as follows −

• Drag the NOC_CountryRegion field from the Medals table to the COLUMNS area.

• Drag Discipline from the Disciplines table to the ROWS area.

• Filter Discipline to display only the five disciplines for which you wanted the report. This can be done either in the PivotTable Fields area, or from the Row Labels filter in the PivotTable itself.

• Drag Medal from the Medals table to the VALUES area.

• Drag Medal from the Medals table to the FILTERS area.

You will get the following PivotTable −

As you observe, Count of Medals is displayed for all the regions and for the five disciplines that you selected. Next, you have to fine-tune this report so that only those regions with total count of medals greater than 80 will be displayed.

• Click the arrow button to the right of Column Labels.

• Click Value Filters in the drop-down list that appears.

• Select Greater Than… from the drop-down list that appears.

Value Filters dialog box appears.

As you observe, Count of Medals and is greater than are displayed in the boxes below Show items for which. Type 80 in the box next to the box containing is greater than and click OK.

Now, the PivotTable displays only those regions with total count of medals in the selected five disciplines greater than 80.

Creating a Relationship between Tables with PivotTable Fields

If you do not import the tables at the same time, if the data is from different sources, or if you add new tables to your workbook, you have to create the relationships among the tables by yourself.

Add a new worksheet with a table that contains Sport and SportID fields to your workbook.

• Name the table — Sports.
• Click ALL in the PivotTable Fields list in the PivotTable worksheet.

You can see that the newly added table- Sports is also visible in the PivotTable Fields list.

Next, add the field Sport also to the PivotTable as follows −

• Drag the field Sport from the table Sports to ROWS area. The Sport values appear as Row labels in the PivotTable.

• A message will appear in the PivotTable Fields list that Relationships between tables may be needed. A CREATE button appears next to the message.

Click the CREATE button. The Create Relationship dialog box appears.

• Select Medals under Table.
• Select Sport under Column.
• Select Sports under Related Table. Sport appears under related column.
• Click OK.

Drag Discipline under Sport in ROWS. This is to define the hierarchy in the PivotTable. The PivotTable displays the Sport and the corresponding group of disciplines for that sport.

Exploring Data with Powerpivot

Click the DESIGN tab.You will find several visualization commands in the Switch Visualization group on the Ribbon.

You can quickly create a number of different data visualizations that suit your data using Power View. The visualizations possible are Table, Matrix, Card, Map, Chart types such as Bar, Column, Scatter, Line, Pie and Bubble Charts, and sets of multiple charts (charts with same axis).

To explore the data using these visualizations, you can start on the Power View sheet by creating a table, which is the default visualization and then easily convert it to other visualizations, to find the one that best illustrates your Data. You can convert one Power View visualization to another, by selecting a visualization from the Switch Visualization group on the Ribbon.

It is also possible to have multiple visualizations on the same Power View sheet, so that you can highlight the significant fields.

In the sections below, you will understand how you can explore data in two visualizations – Matrix and Card. You will get to know about exploring data with other Power View visualizations in later chapters.

Exploring Data with Matrix Visualization

Matrix Visualization is similar to a Table Visualization in that it also contains rows and columns of data. However, a matrix has additional features −

• It can be collapsed and expanded by rows and/or columns.
• If it contains a hierarchy, you can drill down/drill up.
• It can display totals and subtotals by columns and/or rows.
• It can display the data without repeating values.

You can see these the differences in the views by having a Table Visualization and a Matrix Visualization of the same data side by side in the Power View.

• Choose the fields – Sport, Discipline and Event. A Table representing these fields appears in Power View.

As you observe, there are multiple disciplines for every sport and multiple events for every discipline. Now, create another Power View visualization on the right side of this Table visualization as follows −

• Click the Power View sheet in the space to the right of the Table.
• Choose the fields – Sport, Discipline and Event.

Another Table representing these fields appears in Power View, to the right of the earlier Table.

• Click the right Table.
• Click the DESIGN tab on the Ribbon.
• Click Table in the Switch Visualization group.
• Select Matrix from the drop-down list.

The Table on the right in Power View gets converted to Matrix.

The table on the left lists the sport and discipline for each and every event, whereas the matrix on the right lists each sport and discipline only once. So, in this case, Matrix visualization gives you a comprehensive, compact and readable format for your data.

Now, you can explore the data to find the countries that scored more than 300 medals. You can also find the corresponding sports and have subtotals.

• Select the fields NOC_CountryRegion, Sport and Medal Count in both the Table and Matrix Visualizations.

• In the Filters, select the filter for the Table and set the filtering criteria as is greater than or equal to 300.

• Click apply filter.

• Set the same filter to Matrix also. Click apply filter.

Once again, you can observe that in the Matrix view, the results are legible.

Exploring Data with Card Visualization

In a card visualization, you will have a series of snapshots that display the data from each row in the table, laid out like an index card.

• Click the Matrix Visualization that is on the right side in the Power view.
• Click Table in the Switch Visualization group.
• Select Card from the drop-down list.

The Matrix Visualization gets converted to Card Visualization.

You can use the Card view for presenting the highlighted data in a comprehensive way.

Data Model and Power View

A workbook can contain the following combinations of Data Model and Power View.

• An internal Data Model in your workbook that you can modify in Excel, in PowerPivot, and even in a Power View sheet.

• Only one internal Data Model in your workbook, on which you can base a Power View sheet.

• Multiple Power View sheets in your workbook, with each sheet based on a different Data Model.

If you have multiple Power View sheets in your workbook, you can copy visualizations from one to another only if both the sheets are based on the same Data Model.

Creating Data Model from Power View Sheet

You can create and/or modify the Data Model in your workbook from the Power View sheet as follows −

Start with a new workbook that contains Salesperson data and Sales data in two worksheets.

• Create a table from the range of data in the Salesperson worksheet and name it Salesperson.

• Create a table from the range of data in the Sales worksheet and name it Sales.

You have two tables – Salesperson and Sales in your workbook.

• Click the Sales table in the Sales worksheet.
• Click the INSERT tab on the Ribbon.
• Click Power View in the Reports group.

Power View Sheet will be created in your workbook.

You can observe that in the Power View Fields list, both the tables that are in the workbook are displayed. However, in the Power View, only the active table (Sales) fields are displayed since only the active data table fields are selected in the Fields list.

You can observe that in the Power View, Salesperson ID is displayed. Suppose you want to display the Salesperson name instead.

In the Power View Fields list, make the following changes.

• Deselect the field Salesperson ID in the Salesperson table.
• Select the field Salesperson in the Salesperson table.

As you do not have a Data Model in the workbook, no relationship exists between the two tables. No data is displayed in Power View. Excel displays messages directing you what to do.

A CREATE button also will be displayed. Click the CREATE button.

The Create Relationship dialog box opens in the Power View Sheet itself.

• Create a relationship between the two tables using the Salesperson ID field.

Without leaving the Power View sheet, you have successfully created the following −

• The internal Data Model with the two tables, and
• The relationship between the two tables.

The field Salesperson appears in Power View along with the Sales data.

• Retain the fields Region, Salesperson and ∑ Order Amount in that order in the area FIELDS.

• Convert the Power View to Matrix Visualization.

• Drag the field Month to the area TILE BY. Matrix Visualization appears as follows −

As you observe, for each of the regions, the Salespersons of that region and sum of Order Amount are displayed. Subtotals are displayed for each region. The display is month wise as selected in the tile above the view. As you select the month in the tile, the data of that month will be displayed.

Exploring Data with Power View Charts

In Power View, you have a number of Chart options: Pie, Column, Bar, Line, Scatter, and Bubble. The Charts in Power View are interactive. If you click on a value in one chart −

• That value in that chart is highlighted.
• That value in all the other charts in Power View is also highlighted.
• All the tables, matrices and tiles in Power View are filtered to that value.

Thus, Power View Charts serve as interactive, pictorial data analysis tools. Further, the charts are interactive in a presentation setting also, which would enable you to highlight the analysis results.

Exploring with Line Charts

You can use Line charts for comparing data points in one or more data series. Line charts distribute category data evenly along a horizontal (category) axis, and all numerical value data along a vertical (value) axis.

Suppose you want to display the Medal Count for each country.

• Create a Power View with the fields NOC_CountryRegion and Medal Count selected. By default, Table will be displayed.

• Click the Table.

• Click Other Chart in the Switch Visualization group.

• Select Line from the drop-down list. Line Chart will be displayed in the Power View.

• Click on the Line or the Category (x-axis) axis.

• Drag to left or right. The Categories to the left or right will be displayed and Line chart will be displayed accordingly.

• Place the cursor on any of the data points on the line.

The values corresponding to that data point will be displayed at that point.

Exploring with Bar Charts

You can use Bar charts for comparing data points in one or more data series. In a Bar chart, categories are organized along the vertical axis and values along the horizontal axis. In Power View, there are three Bar chart subtypes −

• Stacked Bar.
• 100% Stacked Bar.
• Clustered Bar.

You can convert a Table Visualization to Bar Chart Visualization as follows −

• Create two Table visualizations side-by-side.
• Click the right Table.
• Click Bar Chart in the Switch Visualization group.
• Click Stacked Bar.

The Table Visualization on the right gets converted to Bar Chart Visualization. As you observe, the y-axis values are sorted by the category values in ascending order.

• Take the cursor above the Bar chart. You will find – sort by NOC_CountryRegion asc.

• Click NOC_CountryRegion. It is changed to Medal Count.

• Click asc. It is changed to desc. You will find that the Bar Chart is sorted by descending Medal Count.

• Click the Bar with Category GER. Only that Bar will be highlighted.

• With Ctrl key pressed, click the Bars with Categories FRA and ITA. The Bars for GER, FRA and ITA will be highlighted.

• The Table on the left also shows values for these three Categories only.

In both the visualizations, click the Gender field also in the Power View Fields list.

Click the left portion of the Bar – GER. It is highlighted. In the Table, only the information for GER and Men will be displayed.

Note − You cannot make multiple selections in this case.

Exploring with Column Charts

You can use Column charts for showing data changes over a period of time or for illustrating comparison among items. In Column charts, categories are along the horizontal axis and values along the vertical axis.

In Power View, there are three Column chart subtypes −

• Stacked Column.
• 100% Stacked Column.
• Clustered Column.

You can convert a Table Visualization to Column Chart Visualization as follows −

• Create two Table visualizations side-by-side.
• Click the right Table.
• Click Column Chart in the Switch Visualization group.
• Click Stacked Column.

The Table Visualization on the right is converted to Bar Chart Visualization. As you observe, the x-axis values are sorted by the category values in ascending order.

• Take the cursor to above the Column chart. You will find – sort by NOC_CountryRegion asc.

• Click on NOC_CountryRegion. It gets changed to Medal Count.

• Click on asc. It gets changed to desc. You will find that the Column Chart is sorted by descending Medal Count.

Click on the lower portion of the Bar with Category GER. It gets highlighted.

In the Table, only the information for GER and Men will be displayed.

Exploring with Simple Pie Charts

Pie charts in Power View are simple or sophisticated. You will learn simple Pie charts in this section. You will learn sophisticated Pie charts in the next section.

Start with creating a Pie chart as follows −

• Resize the Stacked Column chart and move it upwards.
• Create another Table visualization below the Stacked Column chart.
• Click the new Table.
• Click Other Chart in the Switch Visualization group.
• Select Pie.

The Table Visualization below the Stacked Column chart is converted to Pie Chart Visualization. As you observe, there are too many slices in the Pie chart as there are many categories (countries). Note that Pie charts work well only when the number of categories is 8 or less.

You can reduce the number of categories by filtering the values as follows −

• Set the filtering as Medal Count is greater than or equal to 1300 in −
  • Table Visualization
  • Column Chart Visualization
  • Pie Chart Visualization

Note − You have to define and apply filtering to each of the visualizations separately.

Now, you have a Simple Pie Chart Visualization, wherein the count of Medals are shown by the Pie size, and countries by colors.

Click on a Pie slice. That slice is highlighted and others get grayed. The corresponding column in the Column chart also is highlighted. In the table, only the values corresponding to the highlighted Pie slice will be displayed.

Exploring with Sophisticated Pie Charts

You can make your Pie Chart Visualization sophisticated, by adding more features. You can make a pie char that −

• Drills down when you double-click a slice, or
• Shows sub-slices within the larger color slices.

A Pie chart that drills down when you double-click a slice

• In the Pie chart, in the Power View Fields list, drag the field Gender to COLOR area, to below the field NOC_CountryRegion. This means you have two categories.

• In the Table, include Gender also in the Fields list.

Your Power View looks as follows −

As you observe, there is a single slice with one color for each category — country.

On the Pie chart, double-click on the USA slice.

The Pie chart in your Power View will be changed to show values by Gender, which is the second category, for the selected category (USA). The colors of the pie chart now show the percentages of the second field, i.e., Gender, filtered for the pie color you doubleclicked. In other words, the Pie chart was drilled down. As you observe, a small arrow appears on the top right corner of the Pie chart. If you place the mouse over it, the arrow is highlighted and Drill up will be displayed.

Click the drill up arrow. The Pie Chart returns to its previous state.

A Pie chart that shows sub-slices within the larger color slices

In the Pie chart, in the Power View Fields list, drag the field Gender from COLOR area to SLICES area.

Your Power View looks as follows −

As you can see, in the Pie chart, there are two slices of same color for the category USA.

Click on one of these slices.

You will be able to see the following changes in Power View −

• The selected slice is highlighted and other slices are grayed or deactivated.
• The bar for the category USA displays the medal count for the selected slice.
• The Table shows the values for the selected slice.

• Click the other slice. You can observe the changes as given above for this selected slice.

Exploring with Scatter Charts

You can use Scatter charts to display many related data in one chart. In Scatter charts, the x-axis displays one numeric field and the y-axis displays another, making it easy to see the relationship between the two values for all the items in the chart.

To create a Scatter Chart Visualization, proceed as follows −

• Add the fields Sport, Medal Count and Event to Table.

• Click the arrow next to Event in the Power View Fields list. Click Count (Distinct). The field Event changes to the numeric field Count of Event. Therefore, you have one category field – Sport and two numeric fields – Medal Count and Count of Event.

• Click Other Chart in the Switch Visualization group.

• Click Scatter.

You will get the Scatter Chart Visualization, with the data points displayed as circles of same size, showing how the Count of Event and Medal Count values are related for each sport.

• Click the LAYOUT tab on the Ribbon.
• Click Data Labels in the Labels group.
• Select Right from the drop-down list. The Data labels appear for the data points.

The sport Wrestling has less number of medals in more number of events as compared to the sport Aquatics that has more number of medals in less number of events.

Exploring with Bubble Charts

You can use Bubble charts to display many related data in one chart. In Bubble Charts, the x-axis displays one numeric field and the y-axis displays another, making it easy to see the relationship between the two values for all the items in the chart. A third numeric field controls the size of the data points.

To create a Bubble Chart Visualization, proceed as follows −

• Drag Medal Count to Size.
• Drag NOC_CountryRegion to ∑ X-VALUE. The Scatter chart is converted to Bubble chart.

As you observe, the size of each bubble shows the medal count. The data labels show the Sport.

Exploring with Colors

You can also color the bubbles by a category as follows −

• Drag the field NOC_CountryRegion to COLOR area in the Power View Fields list.
• Drag the field DiscipleEvent to ∑ X-VALUES.

As you observe, Legend shows the values of the category that is in COLOR area and the respective colors. The data labels correspond to the category in DETAILS area. The size of the data points is by the area ∑ SIZE.

Next, you can see how selecting a category in Legend changes the visualization −

Click on a value in the Legend. Only the data points of that color (i.e., corresponding to that value) will be highlighted. All the other data points will be deactivated.

As you observe, all the sports corresponding to the selected country are displayed and the size of each bubble represents the medal count.

If you want to know the details of a single data point −

• Highlight the data point by just clicking on that bubble.
• Place the cursor on that data point.

Only that bubble is highlighted and the rest of the bubbles get grayed. All the information about that data point will be displayed in a box next to the data point.

Exploring with Play Axis

You can visualize the data changes over a period of time using Play Axis as follows −

• Drag the field Edition in the Power View Fields list to PLAY AXIS area.

A timeline with a Play button is inserted in your Bubble chart visualization. You can adjust the timeline by filtering the Edition field values in the Filters. This would be useful if you want to focus on a particular time range or if the timeline is too wide.

• Adjust the timeline by filtering Edition field in Filters and choosing a span of time values.

• Click the Play button. The bubbles travel, grows and shrink to show how the values change based on the play axis. A small vertical line appears on the timeline that moves across the timeline. The time at that point also is displayed.

You can pause at any point to study the data in more detail.

Exploring Data with Power View Maps

You can use maps to display your data in the context of geography. Maps in Power View use Bing map tiles, so you can zoom and pan as you would with any other Bing map. To make maps work, Power View has to send the data to Bing through a secured web connection for geocoding. So, it asks you to enable content. Adding locations and values places dots on the map. The larger the value, the bigger the dot. When you add a multivalue series, you get pie charts on the map, with the size of the pie chart showing the size of the total.

Exploring Data with Geographic Fields

You can create a Power View Map Visualization if your data has a geographic field such as Country/Region, State/Province, or City.

To create a map visualization for the medal count, country wise proceed as follows −

• Create a new Power View sheet from INSERT tab on the Ribbon.

• Drag the fields NOC_CountryRegion and Medal Count in the Power View Fields list to the Power View. A Table with these two fields are created.

So, you have a geographic field and a numeric field.

• Click the DESIGN tab on the Ribbon.
• Click Map in the Switch Visualization group.

The Table Visualization converts into Map Visualization.

As you observe, Power View creates a map with a dot representing each geographic location. The size of the dot is the value of the corresponding numeric field, which is the medal count in this case. Further, in the Power View Fields list, the Geographic field will be in the Locations area and the Numeric field will be in the ∑ SIZE area.

To display more information about a data point, you can do one of the following −

• If you place the cursor on a dot on the map, a box appears displaying the geographic location name and the corresponding numeric value.

• If you click on a dot on the map, that particular dot gets highlighted.

Pie Charts as Data Points

Suppose you want to add another field also to the map visualization. For example, you might want to display the details about the medals, viz. the medal types – Gold, Silver and Bronze. You can do it as follows −

• Drag the field Medal from the Power View Fields list to the COLOR area.

The dots are converted to Pie charts. A Legend for Medal appears displaying the types of medals and respective colors. i.e., each color in the Pie chart represents the type of the medal.

You can observe that the size of a Pie chart corresponds to the medal count and the size of each slice in the Pie chart corresponds to the count of that medal type.

Highlighting a Data Point

Now, you can filter your data and highlight a significant data point as follows −

• In the Filters area, set the Medal Count to display only the values greater than or equal to 300.

• Apply the filter. The map zooms and displays only the filtered values.

Place the cursor on the dot representing Great Britain. The dot gets highlighted and zoomed. The details of the Pie chart will be displayed.

As you can see, the medal count for gold for Great Britain is 514. You can find the medal counts for silver and bronze by placing the cursor on those slices.

Highlighting a Pie Slice in a Data Point

Next, you might want to highlight the gold medal count of Great Britain.

• Place the cursor on the slice with red color (as you can make out that red represents gold in the Legend). Click it.

That Pie Slice will be highlighted. The other slices in that Pie chart and all the other Pie charts will be deactivated.

Place the cursor on the dot again. The dot is zoomed. The slice representing gold will be highlighted. The details of the slice will be displayed.

Exploring Data with Power View Multiples

Multiples, also called Trellis Charts are a series of charts with identical X and Y axes. You can arrange Multiples side by side, to compare many different values easily at the same time.

• You can have Line charts, Pie charts, Bar charts and Column charts as Multiples.
• You can arrange the Multiples horizontally or vertically.

Line Charts as Multiples

You might want to display the medal count by year for each Region. Firstly, you need to have the field Year. To get this field, you need to have a calculated column as follows −

• Click the Medals tab in the Data View of the Data Model (in the PowerPivot window).
• Click in the first cell in the right most column with the header Add Column.
• Type =YEAR ([Edition]) in the formula bar and press Enter.

A new column with header CalculatedColumn1 is created with values corresponding to the Year values in Edition column.

Click on the header and rename it as Year.

• Close the PowerPivot window. The Data Model gets updated. The new field — ∑ Year appears in the Power View Fields list.

• Create a Table in Power View with fields NOC_CountryRegion, Count of Year and Medal Count, by dragging the fields.

• Convert Table into a Line chart in Power View.
• Remove the field NOC_CountryRegion. A Line chart appears with Medal Count by Year.

As you can observe, Year is in AXIS area and Medal Count is in ∑ VALUES area in Power View Fields list. In the Line chart, Year values are on X-axis and Medal count on Y-axis.

Now, you can create Multiples visualization with Line charts, as follows −

• Drag the field NOC_CountryRegion to VERTICAL MULTIPLES area in the Power View Fields list.
• Click the tab LAYOUT on the Ribbon.
• Click Grid Height in the Multiples group.
• Click a value in the dropdown list.

• Click Grid Width in the Multiples group.
• Click on a value from the dropdown list.

You will get the Multiples Visualization with Line charts arranged as a grid, with each Line chart representing a country (NOC_CountryRegion).

Vertical Multiples

As you are aware, you have placed the NOC_CountryRegion field in the VERTICAL MULTIPLES area. Hence, the visualization that you have got is the Vertical Multiples visualization. You can observe the following in the chart given above.

• One Line chart per category that is placed in VERTICAL MULTIPLES area, in this case – the country.

• The grid height and grid width that you have chosen determine the number of rows and number of columns for the Multiples.

• A common x-axis for all the multiples.

• A similar y-axis for each row of the multiples.

• A vertical scroll bar on the right side that can be used to drag the rows of Line charts up and down, so as to make the other Line charts visible.

Horizontal Multiples

You can have the Multiples Visualization with Horizontal Multiples also as follows −

• Drag the field NOC_CountryRegion to VERTICAL MULTIPLES area.
• Click the Layout tab on the Ribbon.
• Select the values for Grid Height and Grid Width in the Multiples group.

You will get the Horizontal Multiples visualization as follows −

You can observe the following in the above chart −

• One Line chart per category that is placed in HORIZONTAL MULTIPLES area, in this case – the country.

• The grid height that you have chosen determines the height of the Line charts, unlike the number of rows of Line charts as is the case in the VERTICAL MULTIPLES. In other words, there is a single row of Line charts with the height determined by the Grid Height that is chosen.

• The grid width that you have chosen determines the number of columns of Line charts in the row.

• A common x-axis for all the multiples.

• A common y-axis for all the multiples.

• A horizontal scroll bar at the bottom, below the x-axis, that can be used to drag the row of Line charts to the left and the right, so as to make the other Line charts visible.

Pie Charts as Multiples

If you want to explore / visualize more than one category in Multiples, Pie charts is an option. Suppose you want to explore the medal count by medal type for each of the countries. Proceed as follows −

• Click the Design tab.
• Select Pie from the dropdown under Other Chart.
• Drag Medal to the area SLICES.

You will get the Horizontal Multiples visualization with Pie charts, as you have the field NOC_CountryRegion in the area HORIZONTAL MULTIPLES.

As you can observe the medal-count for each country is displayed as a Pie chart with the slices representing the medal types with the color as given in the Legend.

Suppose you want to highlight the count of gold medals for all the countries. You can do it in a single step as follows −

Click on the blue color slice one of the Pie charts (as blue is color for Gold as per the Legend). In all the Pie charts, only the blue slices are highlighted and other slices are grayed.

As you can observe, this gives a fast way of exploring and comparing the count of gold medals across the countries.

You might want to display more number of Pie charts in a visualization. You can do it by simply switching over to Vertical Multiples Visualization and choosing the right values for Grid Height and Grid Width for a proper display.

Click on the blue slice on one of the Pie charts. The blue slices in all the Pie charts are highlighted so that you can compare the gold medal counts across the countries.

Bar Charts as Multiples

You can choose Bar charts also for Multiples visualization.

• Switch over to Stacked Bar visualization.
• Adjust the Grid Height and Grid Width to get a proper display of the Bar charts.

With Grid Height of 6 and Grid Width of 2, you will get the following −

You can have Clustered Bar charts also for this visualization.

Column Charts as Multiples

You can choose Column charts also for Multiples visualization.

• Switch over to Stacked Column visualization.
• Adjust the Grid Height and Grid Width to get a proper display of the Column charts.

With Grid Height of 2 and Grid Width of 6, you will get the following −

You can have Clustered Column charts also for this visualization.

Wrap-up

The fields you choose depend on what you want to explore, analyze and present. For example, in all the visualizations above, we have chosen Medal for Slices that helped to analyze medal count by medal type. You might want to explore, analyze and present the data gender-wise. In such a case, choose the field Gender for Slices.

Once again, the visualization that is suitable also depends on the data you are displaying. If you are not sure about the suitability, you can just play around to choose the right one as switching across the visualizations is quick and simple in Power View. Moreover, you can also do it in the presentation view, in order to answer any queries that can arise during a presentation.

Exploring Data with Power View Tiles

Suppose you have lot of data to display with significant data points at varied places. In such a case, you might have to scroll very often in your Power View visualizations to find the data you are looking for. This would be tedious and also might not be smooth when you are presenting the results.

You can overcome this drudgery, using the tile feature in Power View. With tiles, you can gain insights from your data much more quickly. Tiles act as navigation strips, with a single tile for each possible field value. When you click on a tile, only data related to that field value is displayed. As it is easy to scroll the values in the navigation strip that dynamically changes the corresponding values in the visualization, tiles become an easy to use tool for you.

You can have Tiles in a Table, Matrix, Card or Chart visualization. You can have a combination of these in Power View and get them filtered with Tiles. A Tile can be simple text or an image.

Table with Tiles

Start with a Table Visualization as follows −

• Drag the fields NOC_CountryRegion, Sport and Medal Count to Power View. As you observe, as the number of rows is large, it is difficult to scroll up and down to highlight values.

• Drag the field Sport from FIELDS area to TILE BY area in the Power View Fields list.

Navigation Strip appears at the top of the Table.

You can observe the following −

• By default, the first Tile in the Navigation Strip is selected.

• In the Table, the values are filtered to that of the Tile selected. In this case, the Sport that is selected.

• There are arrow buttons at the left and right edges of the Navigation strip to enable scrolling.

You can select a different Tile as follows −

• Scroll the Navigation Strip to display the Tile representing the Sport you are looking for, for e.g. Badminton.

• Click the Tile – Badminton. The values in the Table are filtered to those of Badminton.

You can observe the medal count Total is also displayed. You have an option to turn Totals on or off from the Ribbon. You also can make the Tiles more appealing and meaningful by having images in place of Text.

• Include a column that has hyperlinks to the image files corresponding to each of the Sports.

• Include that field, for e.g. Discimage in TILE BY. You will get the Tiles as images, portraying each sport.

Tile Navigation Strip — Tab Strip

There are two types of navigation strips in Excel — Tile Flow and Tab Strip.

In a Tab strip, you can observe the following −

• Tab strip displays the navigation strip across the top of the Visualization.

• By default, the first Tile in the navigation strip that is the leftmost is selected.

• There are arrow buttons at the left and right edges of the navigation strip to enable scrolling.

• You can scroll to the left or right to display the Tiles.

• The highlighted Tile moves to the left or right as you scroll the tab strip. It can also go out of view, while scrolling.

• You can click on a Tile to select it. The Tile gets highlighted at the same position as it was before.

• In the Table, the values are filtered to that of the Tile selected. In this case, the Sport that is selected.

Tile Navigation Strip — Tile Flow

You can covert the navigation strip from tab strip to tile flow as follows −

• Click a Tile on the navigation strip.
• Click the DESIGN tab on the Ribbon.
• Click Tile Type in the Tiles group.
• Click Tile Flow in the dropdown list.

The navigation strip shifts to the bottom of the Table.

In a Tile Flow, you can observe the following −

• Tile flow displays the navigation strip across the bottom of the Visualization.

• By default, the first Tile in the navigation strip is selected. It will be displayed at the center of the tile flow.

• There are no arrow buttons for scrolling.

• You can scroll to the left or right by clicking on any of the Tiles to the left or right of the center Tile.

• The Tiles flow to the left or right and the center Tile will always get highlighted.

• You can click on a Tile to select it. The Tile gets highlighted and moves to the center of the Tile flow.

• As the selected Tile is always the center Tile, the following happens −

  • Selected Tile does not go out of view.

  • When you scroll to the left or right, the Tile that comes to the center position gets automatically selected and highlighted.

  • The original selection disappears.

  • The Visualization, Table in this case, automatically is updated to the Tile in the center of the Tile flow.

• In the Table, the values are filtered to that of the Tile selected. In this case, the Sport that is selected.

Matrix with Tiles

Suppose you want the medal count by medal type – Gold, Silver and Bronze and also the total medal count, by country for a selected sport, you can display the results in a Matrix Tile visualization.

• Switch Visualization to Matrix.
• Add the field Medal to Matrix.

You will get the desired results as follows −

Stacked Bar Chart with Tiles

You can make your explored results more conspicuous by switching your visualization to Stacked Bar Chart Tile Visualization −

Maps with Tiles

As your data contains geographic locations, you can also switch over to Map Tile Visualization −

Exploring Data with Hierarchies

If your data more number of levels, it would be easy for you to explore and present it with Hierarchies. For any data value in your Hierarchy, you can drill down to display more details or drill up to have a holistic view.

If your data model has a hierarchy, you can use it in Power View. Otherwise, you can create a hierarchy in the Power View itself with few easy steps.

Creating a Hierarchy in Power View

In Power View a Hierarchy is best depicted in Matrix visualization. Create a Hierarchy in Matrix visualization as follows −

• Drag the fields NOC_CountryRegion, Sport, Discipline, Year and Medal – in that order to ROWS area.

• Drag the field Medal Count to ∑ VALUES. The order of the fields in the ROWS area defines the Hierarchy in Power View.

• If you are not sure about the order of fields, start with any order and then rearrange them in the ROWS area by dragging them up and down, while looking at the display in the Power View.

You will get the following Matrix visualization showing the five Hierarchy levels −

As you observe, the levels are nested.

Drilling Up and Drilling Down the Hierarchy

You can drill up and drill down the hierarchy such that you can show just one level at a time. You can drill down for details and drill up for summary.

To enable drill up and drill down, first set up show levels option as follows −

• Click the DESIGN tab on the Ribbon.
• Click Show Levels in the Options group.
• Select Rows – Enable Drill Down One Level at a Time from the drop-down list.

The Matrix collapses to display only Level 1 data.

As you observe, when you click on each of the data items, a downward arrow appears on the right side for that item indicating drill down.

Now, you can drill down the data one level at a time as follows −

• Click Level 1 data item for which you want further details. For example, click AUS. As you observe, Medal Count for AUS is 1079.

• Click on the arrow to the right side of it. Alternatively, you can double click on the data item.

• Level 2 data pertaining to AUS will be displayed.

As you observe, an upward arrow appears on the left side of the first item, indicating drill up and when you click on each of the data items, a downward arrow appears on the right side for that item indicating drill down.

Now, you can drill down the data one more level as follows −

• Click Level 2 data item for which you want further details. For example, click Aquatics. As you observe, the medal count for Aquatics is 354.

• Click on the arrow to the right side of it.

• Level 3 data pertaining to Aquatics will be displayed.

As you observe, an upward arrow appears on the left side of the first item, indicating drill up and when you click on each of the data items, a downward arrow appears on the right side for that item indicating drill down.

Now, you can drill down the data one more level as follows −

• Click Level 3 data item for which you want further details. For e.g. click on Diving. As you observe, the medal count for Diving is 17.

• Click on the arrow to the right side of it.

• Level 4 data pertaining to Diving will be displayed.

As you observe, an upward arrow appears on the left side of the first item, indicating drill up and when you click on each of the data items, a downward arrow appears on the right side for that item indicating drill down.

Now, you can drill down the data one more level as follows −

• Click on the Level 4 data item for which you want further details. For example, click on 2008. As you observe, the medal count for 2008 is 3.

• Click on the arrow to the right side of it.

• Level 5 data pertaining to 2008 will be displayed.

As you observe, for the first Level 5 data item an upward arrow appears on the left side indicating drill up. Drill down arrows do not appear on the right side for the data items as there are further levels to drill down.

Now, you can drill up the data one level at a time by clicking on the upward arrow to the left side of the first item at each Level.

Exploring a Hierarchy in Stacked Bar Chart

You might want to highlight certain values in a hierarchy in a significant way. In such a case, you can use a chart visualization, such as Stacked Bar chart as follows −

• Click the Matrix visualization and switch to Stacked Bar Chart.
• Drag the field Medal to LEGEND area.

You will get the Stacked Bar chart visualization as follows −

In this case, you need to double-click on a Bar to drill down.

Double-click on Bar representing AUS. The chart is drilled down to display the next level of data in the hierarchy.

As you can observe, an upward arrow indicating drill up appears at the top-right corner of the chart.

Drill down one more level by double-clicking on Aquatics Bar. The chart is drilled down to display the next level of data in the hierarchy.

You can drill down by double-clicking on a Bar or drill up by clicking on the drill up arrow on the top-right corner of the chart.

This gives you an interactive exploration of data during presentation also.

Aesthetic Power View Reports

You have learnt how to explore data interactively using Power View in the earlier chapters of this tutorial. Each Power View sheet can in turn be used as an interactive report. To make the Power View report more appealing, you can choose any of the themes, chart palettes, fonts and background colors that Power View provides you.

When you change the theme, the new theme applies to all the Power View visualizations in the report. Further, you can add background images, choose background formatting, format numbers, and change the Font or the text size.

Report Layout Finalization

As with any other report, you need to first decide on what you are going to report and the best layout so that you can highlight the significant data points.

Suppose you need to report the details of the medals won by Australia in aquatics. As you are aware, the details include the disciplines in aquatics, medal count, and the medal types (Gold, Silver and Bronze).

You can have three views in the report for the best portrayal of the data points in this case −

• Matrix that contains the data — country, sport, and medal count.
• Card that contains the data – country, sport, discipline and medal Count.
• Stacked Bar chart that contains the data that is drilled down to discipline, medal and medal count.

As you can observe, the data in the Matrix and Card is scrolled so that −

• Matrix displays the details of Australia for all sports and aquatics got 354 medals.

• Card displays Australia – sport aquatics, disciplines Diving, Swimming and Water polo and medal count in each of them.

• Stacked Bar chart displays the medal count by medal type in these three disciplines.

Now that the report layout is ready, you can start making it appealing. However, you need to keep two points in mind during this task −

• The look of the report should be based on the audience (Managers / Top Management / Clients).

• Do not get over bored with the different formatting options. Just keep it simple and highlight the data points that require attention.

In the following sections, you will understand how to arrive at a sample report with the following options −

• Selecting the Background.
• Selecting the Theme.
• Changing the Font.
• Changing the Text Size.

Selecting the Background

You can have a background color for your Power View Report. By default, it is white. You can change it with the Background command.

• Click the POWER VIEW tab on the Ribbon.
• Click Background in the Themes group.

Your sample report is ready.

Key Performance Indicators

Key Performance Indicators (KPI) are a set of quantifiable measures that an organization uses to measure its performance over time. KPIs are normally used to evaluate the success of an organization as a whole or department-wise (e.g. sales, finance, etc.). You need to define the KPIs based on the organization objectives and monitor them from time to time to track the progress.

There are a number of KPI types to choose from based on your requirements. Examples include −

• Income and Expenses
• Rate of Return
• Average Purchase Value
• Customer Lifetime Value
• Working Capital

Note that KPIs are a form of communication involving the following activities −

• Identifying the KPIs based on the organization’s objectives.

• Monitoring and reporting the KPIs.

• Altering the KPIs as the organization progresses and / or the organization’s goals change.

Identifying the KPIs

The first and the most crucial step in KPI analysis is to identify the KPIs that effectively monitor the required trends in the organization. This requires complete understanding of the objectives and requires proper communication channels between the analysts and those who are responsible for fulfilling the objectives.

There are a number of KPIs to choose from, but the success in monitoring relies on the right choice of those that are relevant to the objectives. The KPIs differ from organization to organization and from department to department and will be effective only when they lead to improvement in the performance.

You can evaluate the relevance of a KPI using the SMART criteria – i.e. the KPI should be Specific, Measurable, Attainable, Relevant and Time-bound. In other words, the KPI chosen should meet the following criteria −

• The KPI reflects your Specific objective.

• The KPI enables you to Measure progress towards that goal.

• The goal for which the KPI is being defined is realistically Attainable.

• The goal that the KPI is targeting is Relevant to the organization.

• You can set a time-frame for achieving the goal so that the KPI reveals how near the goal is as compared to the time that is left.

The defined KPIs are to be evaluated from time to time to find their relevance as the time progresses. If required, different KPIs need to be defined and monitored. Only then, your KPI monitoring will be relating to the current organization needs.

Based on the analysis needs, you have to choose the relevant KPIs, and examples include the following −

• Sales department might use a KPI to measure monthly gross profit against projected gross profit.

• Accounting department might measure monthly expenditures against revenue to evaluate costs.

• Human resources department might measure quarterly employee turnover.

• Business professionals frequently use KPIs that are grouped together in a business scorecard to obtain a quick and accurate historical summary of business success or to identify trends or to identify performance improvement opportunities.

The examples used in this chapter are indicative so as to help you in understanding how you can define and monitor KPIs in Excel. The sole discretion of identifying the KPIs lies with you based on the objectives so as to reflect the current scenario as compared to the targets.

KPIs in Excel

• You can analyze performance against the set target with PowerPivot. For e.g., a PowerPivot KPI could be used to determine for each year and salesperson how his actual sales compared to his sales target.

• You can explore and visualize the same KPI with Power View.

• You can also define new KPIs and /or edit them in Power View.

• You can produce aesthetic reports with KPIs in Power View.

Defining a KPI in Excel

The first step in KPI analysis is to define the identified KPI. This requires defining the three parameters for the KPI as follows −

Base Value

A Base Value is defined by a calculated field that resolves to a value. The calculated field represents the current value for the item in that row of the table. E.g., aggregate of sales, profit for a given period, etc.

Target Value/ Goal

A Target Value (or Goal) is defined by a calculated field that resolves to a value, or by an absolute value. It is the value against which the current value is evaluated. This could be a fixed number, for example, average number of sick-leave days that is applicable to all the employees, or a calculated field, which results in a different goal for each row, for example, budget of each department in the organization.

Status

Status is the indicator of the value. It would be striking if you set it as visual indicator. In Power View in Excel, you can edit the KPI, choosing which indicators to use and what values to trigger each indicator.

For example, suppose you want to monitor the Sales targets of the Salespersons in an organization who are selling a product. The objective of the analysis is to identify the best performers who are meeting the target Sales Amount. You can proceed to define the KPI as follows −

• Base Value − Current Value of the Sales Amount for each salesperson.

• Target Value / Goal − This is fixed for all the salespersons so as to enable comparison between the salespersons. Assume that the Target Sales Amount is 3500. Note that for a different analysis you could vary the target values for the salespersons.

• Status − The Status is to be displayed with a graphic to easily determine the status of the Base Value compared to the Target Value.

KPIs in PowerPivot

You can define KPIs in PowerPivot as follows −

• Start with two tables SalesPerson and Sales.
  • SalesPerson table contains SalesPerson ID and SalesPerson Name.
  • Sales table contains the sales information salesperson-wise and month-wise.
• Add the two tables to Data Model.
• Create a relationship between the two tables using the field SalesPerson ID.

To set the Base Value, you need a calculated field for Sales Amount.

• Add the calculated field in the Sales table for Sales Amount column in the Data Model as follows −

Total Sales:= sum([Sales Amount])

• Click on PivotTable on the Ribbon in the PowerPivot window.
• Select New Worksheet in the Create PivotTable dialog box.

• Add the field Salesperson to ROWS area in the PivotTable.
• Click on the POWERPIVOT tab on the Ribbon.
• Click on KPIs in the Calculations group.
• Click on New KPI in the dropdown list.

Key Performance Indicator (KPI) dialog box appears.

• Select Total Sales in the KPI base field (value) box.

• Under KPI Status, have the following options −

  • Under Define target value, select Absolute value and type 3500 in the box.

  • Under Define status thresholds, adjust the vertical bars representing the percentages to 40 and 80.

  • Under Select icon style, select the first option.

Click on the OK button. You can observe the following in the Sales table in PivotTable Fields list −

• Total Sales field is a KPI and is depicted by the icon .

• The three KPI parameters – Value, Goal and Status appear as fields under Total Sales KPI.

• Select the three KPI parameters – Value, Goal and Status under Total Sales.

• The three columns appear in the PowerPivot, with the Status column displaying the icons as per the corresponding value.

You can also define the KPI thresholds by values instead of percentages. To modify a defined KPI, proceed as follows −

• Click on KPIs in the Calculations group on the Ribbon.
• Click on Manage KPIs in the dropdown list.

Manage KPIs dialog box appears.

• Click on the KPI – Total Sales.
• Click on the Edit button.

Key Performance Indicator (KPI) dialog box appears.

• Under Define status thresholds, adjust the vertical bars to 1500 and 3000.
• Retain the rest of the earlier options.
• Click on OK.

As you can observe, the status icons reflect the changed thresholds.

KPIs in Power View

You can create aesthetic reports with KPIs in Power View. You can either use the prior defined KPIs in Data Model or you can add KPIs in Power View.

To add or edit a KPI in Power View, proceed as follows −

• In the Power View Sheet, click on the PowerPivot tab.

The PowerPivot Ribbon appears, which you had used in the previous section.

• Click on KPIs in the Calculation group.
• Click on New KPI to add a KPI.
• Click on Manage KPIs to edit a KPI.

The steps are the same as in the previous section.

You can create an aesthetic report of Sales Performance with KPIs in Power View as follows −

• Click on DATA tab on the ribbon.
• Click on Power View in the Reports group.

Power View sheet appears.

• Add a Table with the fields – Salesperson, Total Sales and Total Sales Status.

• Add a second Table with the fields – Salesperson, Total Sales and Total Sales Goal.

• Convert the second Table to 100% Stacked Bar.

• Add a third Table with the fields – Salesperson, Region, Total Sales and Total Sales Status.

• Convert the third Table to Card. Drag the field Region to Tile By.

• Add the Title – Sales Performance.

• Change the font.

• Increase the Text Size.

• Resize Table, 100% Stacked Bar and Card appropriately.

Your Sales Performance report is ready −

As you can observe, in the Power View you could portray the results as follows −

• Table with icons for KPI status is similar to the PowerPivot report.

• 100% Stacked Bar depicts the percentage achieved with respect to the Goal. You can also notice that it gives a clear comparison of the performance of all.

• Card depicts the KPI status of the Salespersons along with the Region they belong to. You can interactively scroll through the Tiles to display results for different Regions that would give scope to assess performance region-wise also.
