STDEVP
Returns the population standard deviation.
Syntax:
STDEVP(number1; number2; ... number30)
- number1 to number30 are up to 30 numbers or ranges containing numbers.
- STDEVP returns the standard deviation where number1 to number30 are the entire population. If you only have a sample of the population use STDEV instead. For a population of N values, the calculation formula is:
-
.
Example:
STDEVP(3; 3; 7; 7)
- returns 2.

Issues:
- Calc assumes that logical values are 1 (TRUE) and 0 (FALSE). Excel ignores logical values.
