The _____ is a measure of the proportion of variance in one of the variables that is accounted for by the other variable.
A)Spearman rank-order correlation coefficient
B)coefficient of determination
C)point-biserial correlation coefficient
D)Pearson product-moment correlation coefficient

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, is the measure of the proportion of variance in one variable that can be explained by the other variable. It is calculated as the square of the Pearson product-moment correlation coefficient between the two variables. Therefore, option B is the correct answer. Options A and C are specific types of correlation coefficients, while option D is the correlation coefficient itself, not the measure of the proportion of variance.
