AVERAGE function

This article describes the formula syntax and usage of the AVERAGE function in Microsoft Excel.

Description

Returns the average (arithmetic mean) of the arguments. For example, if the range A1:A20 contains numbers, the formula = AVERAGE( A1:A20) returns the average of those numbers.

Syntax

The AVERAGE function syntax has the following arguments:

Number1 Required. The first number, cell reference, or range for which you want the average.

Number2, . Optional. Additional numbers, cell references or ranges for which you want the average, up to a maximum of 255.

Arguments can either be numbers or names, ranges, or cell references that contain numbers.

Logical values and text representations of numbers that you type directly into the list of arguments are not counted.

If a range or cell reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.

Arguments that are error values or text that cannot be translated into numbers cause errors.

If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the AVERAGEA function.

If you want to calculate the average of only the values that meet certain criteria, use the AVERAGEIF function or the AVERAGEIFS function.

Note: The AVERAGE function measures central tendency, which is the location of the center of a group of numbers in a statistical distribution. The three most common measures of central tendency are:

Average, which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.

Median, which is the middle number of a group of numbers; that is, half the numbers have values that are greater than the median, and half the numbers have values that are less than the median. For example, the median of 2, 3, 3, 5, 7, and 10 is 4.

Mode, which is the most frequently occurring number in a group of numbers. For example, the mode of 2, 3, 3, 5, 7, and 10 is 3.

For a symmetrical distribution of a group of numbers, these three measures of central tendency are all the same. For a skewed distribution of a group of numbers, they can be different.

Tip: When you average cells, keep in mind the difference between empty cells and those containing the value zero, especially if you have cleared the Show a zero in cells that have a zero value check box in the Excel Options dialog box in the Excel desktop application. When this option is selected, empty cells are not counted, but zero values are.

To locate the Show a zero in cells that have a zero value check box:

On the File tab, click Options, and then, in the Advanced category, look under Display options for this worksheet.

Example

Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. For formulas to show results, select them, press F2, and then press Enter. If you need to, you can adjust the column widths to see all the data.

Average a group of numbers

You may have used AutoSum to quickly add numbers in Excel. But did you know you can also use it to calculate other results, such as averages?

Use AutoSum to quickly find the average

AutoSum lets you find the average in a column or row of numbers where there are no blank cells.

Click a cell below the column or to the right of the row of the numbers for which you want to find the average.

On the HOME tab, click the arrow next to AutoSum > Average, and then press Enter.

You may have used AutoSum to quickly add numbers in Excel.

But did you know you can also use it to calculate other results, such as averages?

Click the cell to the right of a row or below a column. Then, on the HOME tab, click the AutoSum down arrow, click Average, verify the formula if what you want, and press Enter.

When I double-click inside the cell, I see it is a formula with the AVERAGE function.

The formula is AVERAGE, A2, colon, A5, which averages the cells from A2 through A5.

When averaging a few cells, the AVERAGE function saves your time. With larger ranges of cells, it’s essential.

If I try to use the AutoSum, Average option here, it only uses cell C5, not the entire column.

Why? Because C4 is blank.

If C4 contained a number, C2 through C5 would be an adjacent range of cells that AutoSum would recognize.

To average values in cells and ranges of cells that aren’t adjacent, type an equals sign (a formula always starts with an equals sign), AVERAGE, open parenthesis, hold down the Ctrl key, click the desired cells and ranges of cells, and press Enter.

The formula uses the AVERAGE function to average the cells containing numbers and ignores the empty cells or those containing text.

For more information about the AVERAGE function, see the course summary at the end of the course.

Calculate an average

Excel provides a variety of ways to find the average of a set of numbers. For example, you can use function to calculate a simple average, a weighted average, or an average that excludes specific values.

Use the provided sample data and the following procedures to learn how to calculate averages.

Copy the sample data

To better understand the steps, copy the following sample data to cell A1 on a blank sheet.

Create a blank workbook or sheet.

Select the following sample data.

Note: Do not select the row or column headings (1, 2, 3. A, B, C. ) when you copy the sample data to a blank sheet.

Number of Units Ordered

Average unit quality

Average price per unit

Average quality for all units rated above 5

Press + C .

In the sheet, select cell A1, and then press + V .

Calculate the simple average

Select cells A2 through A7 (the values in the Unit Quality column).

On the Formulas tab, click the arrow next to AutoSum , and then click Average.

The result is 8.166666667.

Calculate the average for nonadjacent cells

Select the cell where you want the average to appear, such as cell A8, which is the cell to the left of the cell that contains the text «Average unit quality» in the sample data.

On the Formulas tab, click the arrow next to AutoSum , click Average, and then press RETURN.

Click the cell that contains the average that you just created, cell A8 in this example.

The formula is displayed in the formula bar, =AVERAGE(A2:A7) if you’re using the sample data.

In the Formula Bar, select the content between the parentheses, which is A2:A7 if you’re using the sample data.

Hold down the key and click the cells that you want to average, and then press RETURN. For example, select A2, A4, and A7, and then press RETURN.

Excel replaces the selected range reference in the AVERAGE function with cell references for the cells that you selected. In this example, the result is 8.

Calculate a weighted average

This example calculates the average price paid for a unit across all orders, where each order is for a different number of units at a different price per unit.

Select cell A9, which is the cell to the left of the cell that contains the text «Average price per unit.»

On the Formulas tab, click Insert Function to open the Formula Builder pane.

In the Formula Builder list, scroll down and double-click SUMPRODUCT.

Tip: To quickly find a function, click the Search for a function box, and then start typing the function name. For example, start typing SUMPRODUCT.

Click the box next to array1, and then on the sheet, select cells B2 through B7 (the values in the Price Per Unit column).

Click the box next to array2, and then on the sheet, select cells C2 through C7 (the values in the Number of Units Ordered column).

In the formula bar, click to the right of the closing parenthesis for the formula, and then type /

If you don’t see the formula bar, on the View menu, click Formula Bar.

In the Formula Builder list, double-click SUM.

Select the range in the number1 box, press DELETE, and then on the sheet, select cells C2 through C7 (the values in the Number of Units column).

The formula bar should now contain the following formula: =SUMPRODUCT(B2:B7,C2:C7)/SUM(C2:C7).

This formula divides the total cost of all the orders by the total number of units ordered, which results in a weighted price per unit average of 29.38297872.

Calculate an average that ignores specific values

You can create a formula that excludes specific values. In this example, you’ll create a formula to calculate the average unit quality for all units that have a rating greater than 5.

Select cell A10, which is the cell to the left of the cell that contains the text «Average quality for all units rated above 5.»

On the Formulas tab, click Insert Function to open the Formula Builder pane.

In the Formula Builder list, double-click AVERAGEIF.

Tip: To quickly find a function, click the Search for a function box, and then start typing the function name. For example, start typing AVERAGEIF.

Click the box next to range, and then on the sheet, select cells A2 through A7 (the values in the Price Per Unit column).

Click the box next to criteria, and then type «>5».

The formula excludes the value in cell A7 from the calculation, and results in an average unit quality of 8.8.

Tip: To use the AVERAGEIF function to calculate an average that excludes zero values in a list of numbers, type «<>0″ in the box next to criteria.

Use the provided sample data and the following procedures to learn how to calculate averages.
