Summary

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

Syntax

STDEVP(value1,value2,...)

Arguments

Each argument can be a cell, a cell range, a float value, or an integer value. This function can have up to 255 arguments.

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:

STDEVP Equation

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.

Data Types

Accepts numeric data for all arguments. Returns numeric data.

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
