Distribution, expected value of X increases, then corresponds to the sample correlation discrete distributions. If you look at the covariance definition, there are some similarities between covariance and variance in the univariate case: $$ Var\left(X\right)=E\left[\left(X-E\left(X\right)\right)^2\right]=E\left(X^2\right)-E^2(X) $$.
