Summary

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

Syntax

COVARIANCE.P(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 determine whether greater income accompanies greater levels of education in a population.

The covariance is calculated as follows, where n and y are the sample means, AVERAGE(array1) and AVERAGE(array2), and n is the sample size.

COVARIANCE.P Equation

Data Types

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

Examples

COVARIANCE.P(J2:J5,L2:L5)

COVARIANCE.P(R2C12:R15C12,R2C14:R15C14)

COVARIANCE.P({7,5,6},{7,4,4}) gives the result 1

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