Formulas and functions > Functions from A to Z > STDEV.S (standard deviation of a sample)

Syntax:

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

Description:

This estimates the standard deviation of a population based on a sample.

The standard deviation indicates the average amount by which the specified values deviate from the mean.

Number1, Number2, etc., are single values, cell ranges or arrays that contain the values to be evaluated (sample).

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 "unbiased" or "n-1" method.

Example:

STDEV.S(2, 2, 3, 4, 1) returns 1.14018

Compatibility notes:

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