"WebA marginal distribution is a distribution of values for one variable that ignores a more extensive set of related variables in a dataset. That definition sounds a bit convoluted, but the concept is simple.

If X and Y have a bivariate normal distribution with correlation coefficient ρ X Y, then X and Y are independent if and only if ρ X Y = 0.
