If you want to follow along with this tutorial, please download the example spreadsheet.
The Excel STDEVP function returns standard deviation based on the entire population. It can be used to measure how widely values are dispersed from the mean value. STDEVP function has been replaced with STDEV.P function, which has the same behavior.
Syntax and arguments
The STDEVP function returns a numeric value.
1. STDEVP function has been replaced with one or more new functions that may provide improved accuracy. Although it is still available now, you should better use the new function from now, avoiding it is not available in future Excel versions.
