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.
Get standard deviation of population
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.
