STDEVPA

Syntax:

STDEVPA ( argument-list )

Description: Computes the standard deviation of an entire population, using the "biased" or "n" method. [Note: STDEVPA assumes that its arguments are the total population. If the data represents a population sample only, STDEVA should be used instead. If logical values and text representations of numbers in a reference are to be excluded as part of the calculation, use STDEVP instead. end note]

Mathematical Formula:

where x is the sample mean AVERAGE(argument-1, argument-2,…, argument-n) and n is the sample size.

Arguments:

Name	Type	Description
argument-list	logical, number, name, text, array, reference. The argument list can also be an array of numbers.	The arguments in argument-list designate the numbers that are the members of the population.

 

Return Type and Value: number – The standard deviation of an entire population.

Arguments can be numbers; names, arrays, or references that contain numbers; text representations of numbers; or logical values, in a reference. Text representations of numbers that are entered directly into the list of arguments are included. Arguments that contain TRUE evaluate as 1; arguments that contain text or FALSE evaluate as zero. If an argument is an array or reference, only values in that array or reference are used. Empty cells and text values in the array or reference are ignored.

[Example:

STDEVPA(123,134,143,173,112,109) results in 21.66153785
