What function would you use to find the mean in the Microsoft Excel document

To find the mean in Microsoft Excel, you would use the function AVERAGE.

Here are the steps to use the AVERAGE function in Excel:

1. Select the cell where you want to display the mean.
2. Type "=AVERAGE(" into the cell (without the quotation marks).
3. Select the range of cells that contain the data for which you want to calculate the mean.
4. Close the function by typing ")" and press Enter.

For example, if you have a list of numbers in cells A1 to A5 and you want to find the mean of those numbers, you would use the formula "=AVERAGE(A1:A5)" in a different cell. Excel will calculate and display the mean value in that cell.
