In statistics, dependence is any statistical relationship between two random variables or two sets of data. Correlation refers to any of a broad class of statistical relationships involving dependence, though in common usage it most often refers to the extent to which two variables have a linear relationship with each other.

A statistical measure that varies between -1 and +1 that indicates the degree two which two things are related. A correlation only indicates that the two variables tend to move together; it does not necessarily mean that one variable causes the other. Learn more in: Return on Investment in Training
