The STDEVP function calculates the standard deviation for a sample set of data. STDEVP has been replaced with a newer function called STDEV.P, which has the same behavior.

Estimated standard deviation
=STDEVP (number1, [number2], ...)
number1 - First number or reference in the sample.
number2 - [optional] Second number or reference.
The STDEVP function calculates the standard deviation in a sample set of data. Standard deviation is a measure of how much variance there is in a set of numbers compared to the average (mean) of the numbers. The STDEVP function is meant to estimate standard deviation for an entire population. If data represents a sample, use the STDEV function.
Note: STDEVP has been replaced with a newer function called STDEV.P, which has identical behavior. Although STDEVP still exists for backwards compatibility, Microsoft recommends that people use the newer STDEV.P function instead.
Standard Deviation functions in Excel
The table below summarizes the standard deviation functions provided by Excel.
To calculate the standard deviation of a data set, you can use the STEDV.S or STEDV.P function, depending on whether the data set is a sample, or represents the entire population. In the example shown, the formulas in...
