Spread for WinForms provides advanced software components that support Excel import/export, full cell customization, an extensive calculation engine with over 450 functions and more, all with zero dependencies on Excel.

## Content



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](/spreadnet/docs/latest/online-formula/formulas-functionsall/formulas-functsRtoS/FunctionSTDEV):

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](/spreadnet/docs/latest/online-formula/formulas-functionsall/formulas-functsRtoS/FunctionSTDEV) 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

## Version Available
