STDEVPA


Returns the population standard deviation (allowing text and logical values).

Syntax:

STDEVPA(number1, number2, ... number30)

number1 to number30 are up to 30 numbers or ranges containing numbers. Logical values and text may also be included.STDEVPA returns the standard deviation where number1 to number30 are the entire population. If you only have a sample of the population use STDEVA instead.
Logical values are regarded as 1 (TRUE) and 0 (FALSE).
Text values are always regarded as zero.
For a population of N values, the calculation formula is:



Example:

STDEVPA(3, 3, 7, 7)
returns 2.
STDEVPA(B1:B4)
where cells B1, B2, B3, B4 contain red, FALSE, 4, 4 returns 2, the population standard deviation of 0, 0, 4 and 4.
