Quizplus · Accepted Answer

r² is the coefficient of determination, which is the square of the simple correlation coefficient obtained by correlating the two variables (option A). It varies between 0 and 1 (option B). It represents the proportion of the total variation in Y that is accounted for by the variation in X (option C). Therefore, all of the above options are correct (option D).
