Highlighting cells to quickly view Average, Count, and Sum in Excel

I recently needed to check my answers after some data analysis in Alteryx.  I computed many averages using a formula in Alteryx, and I wanted to check those results by calculating the average for a few randomly selected rows.  I did this by invoking a helpful tool in Microsoft Excel.  I will illustrate this functionality with some random data.

In Column E, I used a formula to calculate the average of the 3 populations in Columns B, C, and D.  To manually check that the formula is correct, I highlighted the 3 columns for ID #125.  On the bottom right, Excel calculates the average; it’s difficult to see in the picture below, but Excel confirms that the average is 707,154.

Whenever you highlight a range of cells containing numeric data, Excel will provide the average, count, and sum of the selected cells.  I did not know about this functionality when I first began working as a statistician, and I am very glad that I did learn it eventually – it is very useful for checking answers by analyzing a few randomly selected rows in Excel!
