What Is the AVERAGE Function?

In simple terms, the AVERAGE function in Excel calculates the sum of a group of numbers and then divides that sum by the count of those numbers. It’s great for quickly figuring out average values without needing to calculate it manually.

For example:

  • You can calculate the average of a few test scores to see your overall performance.
  • Find the average of daily sales figures to analyze business trends.

Formula Syntax

The syntax for the AVERAGE formula is straightforward:

=AVERAGE(number1, [number2], …)
  • number1: This is the first number or cell reference you want to average.
  • [number2], …: Additional numbers or cell references (optional) you wish to include in the calculation.

Note: You can select specific numbers, individual cells, or even ranges of cells.

Step-by-Step Guide: How to Use AVERAGE in Excel

1. Open Excel

Start by opening your Excel file where you want to calculate the average.

2. Select a Cell

Click on the cell where you want the average result to appear.

3. Type the AVERAGE Formula

In the selected cell, type:

=AVERAGE(

4. Enter the Numbers or Cell Range

  • For specific cells: If you want the average of specific cells like A2, A3, and A4, type:
    =AVERAGE(A2, A3, A4)
  • For a cell range: To calculate the average for a range, like from cell A2 to A10, type:
    =AVERAGE(A2:A10)

5. Press Enter

Once you’ve entered your numbers or range, press Enter. Excel will calculate the average and display the result in your selected cell.

Example :

Let’s look at a couple of examples to see the AVERAGE function in action.

Example 1: Finding the Average Score of Students

Imagine you have students' test scores in cells B2 through B10. To find the average score, you would use:

=AVERAGE(B2:B10)

Excel will add up all the scores and divide by the count, giving you the average score.

Example 2: Calculating the Average Sales for the Week

If you track sales from Monday to Sunday in cells C2 through C8, you can get the weekly average by entering:

=AVERAGE(C2:C8)

This provides insight into the daily sales performance for that week.

Tips and Common Mistakes

  1. Ignoring Empty Cells and Text:
    The AVERAGE formula only includes numbers, ignoring empty cells or cells with text. This is useful when your data set has some missing entries.

  2. Zero Values Are Counted:
    Cells containing "0" are included in the average calculation, which can lower your average value. If you don't want zeros to affect the average, consider using the AVERAGEIF function instead.

  3. Combining AVERAGE with Other Functions:
    You can combine the AVERAGE formula with other functions like SUM, IF, or ROUND for more advanced calculations.
