COVAR

This function returns the covariance, which is the average of the products of deviations for each data point pair in two sets of numbers.

Syntax

COVAR(array1,array2)

Arguments

The two arrays of data in the arguments of this function should meet these criteria:

Remarks

Use this covariance function to determine the relationship between two sets of data. For example, you can examine whether greater income accompanies greater levels of education in a population.

The covariance is calculated as follows, where n is the size of the arrays and mu is the mean.

COVAR Equation

Data Types

Accepts arrays of numeric data for both arguments. Returns numeric data.

Examples

COVAR(J2:J5,L2:L5)

COVAR(R2C12:R15C12,R2C14:R15C14)

COVAR({7,5,6},{7,4,4}) gives the result 1

COVAR({5,10,15,20,25},{4,8,16,32,64}) gives the result 144
