What is Correlation

1.

A statistic that denotes an association between two quantitative variables; however, it does not show causality. Its coefficient indicates a linear relationship between two variables, and its value ranges between -1 and 1. A correlation coefficient that is less (greater) than zero denotes a negative (positive) relationship. If there is no relationship between two variables, the linear correlation coefficient would be zero.

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
