I can't understand the intuition behind Pearson Product-moment correlation coefficient Formula
for bivariate data. The formula is :
$\rho$ = cov(X,Y)/($S_x$ * $S_y$)
where cov is covariance.
$S_x$ and $S_y$ are standard deviations of x and y.
I want to know how that formula come. I searched on net but couldn't find how that formula came.
