Question

Quizplus · Accepted Answer

The percentage of the variation in y that is explained by the regression equation is equal to the coefficient of determination multiplied by 100. Therefore, if the coefficient of determination is 0.81, the percentage of variation in y explained by the regression equation is 0.81 x 100 = 81%.
