This function returns the sample covariance, which is the average of the products of deviations for each data point pair in two sets of numbers.
COVARIANCE.S(array1,array2)
The two arrays of data in the arguments of this function should meet these criteria:
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.
Accepts arrays of numeric data for both arguments. Returns numeric data.
COVARIANCE.S(J2:J5,L2:L5)
COVARIANCE.S(R2C12:R15C12,R2C14:R15C14)
COVARIANCE.S({7,5,6},{7,4,4}) gives the result 1.5
COVARIANCE.S({5,10,15,20,25},{4,8,16,32,64}) gives the result 180
