Formulas and functions > Functions from A to Z > STDEV.P (standard deviation of entire population)

Syntax:

STDEV.P(Number1, Number2 [, Number3 ...])

Description:

This returns the standard deviation of an entire population.

Number1, Number2, etc., are single values, cell ranges or arrays that contain the values to be evaluated. Please note that all values of the entire population have to be specified. To calculate the standard deviation of a sample, use the STDEV.S/STDEV function instead. This returns an estimate of the standard deviation.

If this function refers to empty cells or cells with error values, they are ignored. Likewise, cells that contain text strings or logical values, but these can be entered directly into the list of arguments and thus taken into account.

Note:

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

Example:

STDEV.P(2, 2, 3, 4, 1) returns 1.0198

Compatibility notes:

Microsoft Excel supports this function only in version 2010 or later. The function is unknown in older versions.
