DEVSQ

Previous pageReturn to chapter overviewNext page

 

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
