Thats covariance formula. Its similar to correlation with a squared on the 2 different variables, and then its more similar to ratio of standard deviations of the 2 variables, and then thats more similar to absolute deviations where before the squaring occurs, think about mean absolute deviations, where its just a absolute value rather than square in the numerator and denominator, and then its gets to the actual formula. That describes the buildup conceptually to what covariance is.
