Term Definition
Regression

A statistical application to correlated values that involves building an equation or model that describes the nature of the correlation or relationship. It will typically look like "Y-Response = Constant + Coefficient(X-Predictor)". A correlation measures the linear association between variables as represented by r, but the quality of the regression is measured by squaring the correlation coefficient, or r2. It measures the proportion of variation explained by the regression model.
