Click here for the Excel Data File … WebOct 20, 2024 · Covariance is SSXY divided by n. So divide your right hand side by n, to see that it is the same expression as in terms of expectations. However, usually we compute covariance by dividing it by n-1, not by n (there are practical reasons to do so). That is why in your later formula the denominator is n-1 rather than n. – ttnphns Oct 20, 2024 at 7:33
