DEVSQ

---

Name

Squared deviation

Description

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,...)

Remarks

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.

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 Type

Accepts numeric data for all arguments or an array of numeric data. Returns numeric data. For more information, see Data Type for Each Cell Type.

Example

DEVSQ(B3,B5,B9,B10)
DEVSQ(B3:B14)
DEVSQ(R3C2,R5C2,R9C2)
DEVSQ(R3C2:R3C12)
DEVSQ(35,31,47,51,37,31,58,39)=680.875
