How to Calculate Mean in Excel 2007

1. Enter your the data in column A. For example, if you have four numbers to enter, you would enter them in cells A1 through A4.
2. Determine the range for your data. For example, if you entered four data points, your range would be A1:A4.
3. Enter the formula '=AVERAGE(Range)' into cell B1 to have Excel automatically calculate the average of your data. In this example, since your range equals A1:A4, you would enter '=AVERAGE (A1:A4)' into cell B1 and the average will appear.
