STDEVA

Previous pageReturn to chapter overviewNext page

 

This function returns the standard deviation for a set of numbers, text, or logical values.

Syntax

STDEVA(value1,value2,...)

Arguments

Each argument can be a cell, a cell range, a float value, an integer value, text, or a logical value. There can be up to 255 arguments. TRUE evaluates to 1 and FALSE or text evaluates to 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 "non-biased" or "n–1" method.

The equation for calculating the standard deviation is the same as for STDEV:

where x is the value and n is the number of values

This function assumes that its arguments are a sample of the population.

This function differs from STDEV 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

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

STDEVA(A1:A9)

STDEVA(R1C2,R3C4,R4C5,R7C2)

STDEVA(95,89,73,87,85,76,100,96,96) gives the result 9.3422576382
