The coefficient of determination r², a measure of the goodness of fit of the estimated regression equation, is the ratio of the explained variation in y (SSR) to the total variation in y (SST), and takes on values between 0 and 1.

Question

Quizplus · Accepted Answer

The coefficient of determination, often denoted as $R^2$, indeed measures the proportion of the variance in the dependent variable that is predictable from the independent variable(s), calculated as the ratio of the explained variation (SSR) to the total variation (SST), and it ranges from 0 to 1.
