Correlation: A Measure of Linear Association Between X and Y The population correlation coefficient (X,Y) between two random variables X and Y with expected values of X and Y and standard deviations X and Y is given as: (X,Y) = E{(X-X)(Y-Y)}/ XY where E is the expectation operator. 1. In data and statistical analysis, correlation describes the relationship between two variables or determines whether there is a relationship at all. It's a tool used in research to express relationships between variables without making a statement about cause and effect. Then, the question remains what is that exact nature of this relationship. It implies that X & Y have a cause-and-effect relationship with each other. In a causal relationship, 1 of the variables causes what happens in the other variable . Correlation is a statistical measure that indicates how two or more variables move together. Correlation.
