WebTo find the coefficient of determination (r^2) and the percentage of the total variation that can be explained by the linear relationship: Step 1: Square the value of r. The coefficient of determination (r^2) is simply the square of the linear correlation coefficient (r). So the first step is to calculate r^2 by squaring the value of r. Step 2 ...
