# Coefficient of Determination Calculator

The coefficient of determination, denoted as r^{2} and pronounced as "R squared", is a number that indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. The coefficient of determination calculator uses the Pearson's formula to calculate the correlation coefficient. Enter the X and Y values separated by comma and click calculate the Correlation Co-efficient (r) and Coefficient of Determination (r^{2}).
