STDEVP

This function returns the standard deviation for an entire specified population (of numeric values).

Syntax

STDEVP(number1,[number2],...)

Arguments

This function has these arguments:

Argument	Description
number1	[Required] The first number argument corresponding to a population.
number2, ...	[Optional] Number arguments 2 to 255 corresponding to a population. You can also use a single array or a reference to an array instead of arguments separated by commas.

Remarks

The standard deviation is a measure of how widely values are dispersed from the average value.

The standard deviation is calculated using the "biased" or "n" method.

The equation for calculating the standard deviation for a population is:

where x is the value and n is the number of values.

This function assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the standard deviation using the STDEV function.

This function differs from STDEVPA, which accepts text or logical values as well as numeric values.

Examples

STDEVP(A1,B2,C3,D4,E5,F6)

STDEVP(A1:A9)

STDEVP(R1C2,R3C4,R4C5,R7C2)

STDEVP(95,89,73,87,85,76,100,96,96) gives the result 8.8079649700
