Quizplus · Accepted Answer

Pearson r is a correlation coefficient that measures the strength and direction of the linear relationship between two variables. Squaring the Pearson r gives the coefficient of determination, which represents the proportion of variance in one measure that can be explained by knowing another measure. Therefore, squaring the Pearson r is the best choice for finding the percent of variance in one measure that is accounted for by knowing another measure.
