Make a seven letter scrabble word

Challenge by: Carl Allchin Welcome to Preppin’ Data 2022. When Jonathan and I started Preppin’ back in 2019 I never thought we’d be still thinking up challenges after this long. But we are seeing lots of people still wanting to practice their data prep skills so Jenny , Tom and myself will keep creating fun challenges for you to be ready for data prep challenges.  Data preparation is a skill that is increasingly becoming necessary in the workplace. We are all surrounded with data sets that can help us answer questions that can improve how we work. Rarely is that data ready for analysis. Either the values are messy or the data just simply isn’t structured in a way that makes analysis easy. If you want to know more about what data structures are good for analysis: read this post . I’ve found with most organisations I have worked with, it’s rare someone will get the chance to practice data preparation skills. After all, which company wants to let their employees

Free isn’t always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text?

As Free Text means the answer could be anything, this is what you get — absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in

One of our intentions with Preppin’ Data is to help people understand more about the tool. From questions we receive, we want to use the site to help people get the most out of the tool — not just learn through challenges. A colleague asked today about how to create a Custom SQL query in Prep Builder. She couldn’t find any resources online so hope this helps! 1. Connect to your Server by choosing the type of database it is 2. Enter the server connection details 3. Pick which database you want to connect to 4. Select Custom SQL from the bottom of your list of tables (you may need to scroll through) by draging this on to your flow pane. 5. Enter your Custom SQL in the grey area when you have the ‘Custom SQL’ input selected in your flow pane (not pushing my SQL skills here!) You will then have access to the date you have formed by your Custom SQL query and can use it as a normal data source ie join it, union it or clean it as you would with
