      rxy = Pearson product-moment correlation coefficient. b = sy/sx * rxy. Thus b and rxy are closely related but provide different interpretations. The correlation rxy measures linear association between X and Y, while the regression coefficient measures the size of the change in Y, which can be predicted when a unit change is made in X.

      When the relationship has a straight-line pattern, the Pearson correlation coefficient describes it numerically. We can analyze the data further by finding an equation for the straight line that best describes the pattern. This equation predicts the value of the response(y) variable from the value of the explanatory variable.
