Calculates standard deviation based on the entire population given as arguments. The standard deviation is a measure of how widely values are dispersed from the average value (the mean).
Syntax
STDEVP(number1,number2, ...)
Number1,number2, ... are 1 to 30 number arguments corresponding to a population. You can also use a single array or a reference to an array instead of arguments separated by commas.
Logical values such as TRUE and FALSE and text are ignored. If logical values and text must not be ignored, use the STDEVPA worksheet function.
Remarks
Example
Using the same data from the STDEV example and assuming that only 10 tools are produced during the production run, STDEVP measures the standard deviation of breaking strengths for all the tools.
STDEVP(A2:E3)
equals 26.05
