Status Bar in Excel provides a quicker way to see the average, count, numerical count, minimum, maximum or sum of selected cells.
1. Select a range of cells (in example, by clicking on the A1 cell and press Shift and Down Arrow button).
In above screenshot, by default, there are only three options of average, count and sum.
3. You may add more options or remove by default by clicking right on the status bar.
Click on the option that you want to add on the status bar and click on any cell in the worksheet to disappear the window.
