The Status Bar Quick Functions in Excel

Most people using Excel never noticed them, but everytime you select a range of cells, you get immediate statistical info right under your nose. Have a look at this video, and start noticing and using them by yourself.

Using the Status Bar Quick Functions

Every time you want to get immediate information (a "glimpse") regarding your data, or to get a general impression of it, without the need to save this information in the worksheet.

For example, you have 30 students in your classroom, and you just typed down their names.
If you want to make sure you typed down all of them, you should best use the quick function named “Count”.
