Is it possible to define a coefficient of correlation which is (a) as simple as the classical coefficients like Pearson's correlation or Spearman's correlation, and yet (b) consistently estimates some simple and interpretable measure of the degree of dependence between the variables, which is 0 if and only if the variables are independent and 1 if and …Bradley Reynolds. 3 years ago. Yes, the correlation coefficient measures two things, form and direction. If you have two lines that are both positive and perfectly linear, then they would both have the same correlation coefficient. The only way the slope of the regression line relates to the correlation coefficient is the direction.About Find the Correlation Coefficient r on Your Calculator (TI83/ 84) The correlation coefficient is very useful for understanding how strong the linear relationship is between two variables.
