DEVSQ

In This Topic

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

DEVSQ(*value1*,*value2*, ...)

DEVSQ(*array*)

DEVSQ(*array1*,*array2*,...)

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.

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

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

This function is available in product version 1.0 or later.
