Summary
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.
Purpose
Get standard deviation of population
Return value
Estimated standard deviation
Syntax
=STDEVP (number1, [number2], …)
Arguments
- number1 – First number or reference in the sample.
- number2 – [optional] Second number or reference.
Usage notes
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.
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.
Notes:
- STDEVP calculates standard deviation using the “n” method, ignoring logical values and text.
- STDEVP assumes your data is the entire population. When your data is a sample set only, calculate standard deviation using the STDEV function (or it’s more current replacement, the STDEV.S function).
- Numbers are supplied as arguments. They can be supplied as actual numbers, ranges, arrays, or references that contain numbers.
- The STDEVP function ignores logical values and text. If you want to include logical values and/or numbers as text in a reference, use the STDEVA function.
