# DEVSQ

## Content

This function calculates the sum of the squares of deviations of data points (or of an array of data points) from their sample mean.

## Syntax

`DEVSQ(value1, value2, ...)`

`DEVSQ(array)`

`DEVSQ(array1, array2,...)`

## Arguments

Each argument can be a double-precision floating-point value, an integer value, or an array (cell range) of these. Up to 255 arguments may be included. You can use a single array (cell range) instead of a list of values. You can use multiple arrays (cell ranges) as well.

## Remarks

This is a measure of the variability in a data set.

The sum of squared deviations is calculated as follows, where *n* is the number of values.

If an array or cell reference argument contains text, logical values, or empty cells, the function ignores those values; however, the function includes in calculations cells with the value zero.

## Data Types

Accepts numeric data for all arguments or array of numeric data. Returns numeric data.

## Examples

`DEVSQ(B3,B5,B9,B10)`

`DEVSQ(B3:B14)`

`DEVSQ(R3C2,R5C2,R9C2)`

`DEVSQ(R3C2:R3C12)`

`DEVSQ(35,31,47,51,37,31,58,39)` gives the result 680.875
