This function returns the standard deviation for an entire specified population, including text or logical values as well as numeric values.

Syntax

STDEVPA(value1,value2,...)

Arguments

Each argument can be a cell, a cell range, a float value, text, a logical value, or an integer value. There can be up to 255 arguments. TRUE evaluates as 1. Text or FALSE evaluates as 0.

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 STDEVA function.

This function differs from STDEVP because it accepts text or logical values as well as numeric values.

Data Types

Accepts numeric, text, and logical data for all arguments. Returns numeric data.

Examples

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

STDEVPA(A1:A9)

STDEVPA(R1C2,R3C4,R4C5,R7C2)

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