Question

Quizplus · Accepted Answer

Squaring the correlation coefficient gives you the coefficient of determination which represents the proportion of variance in one variable that can be explained by the other variable. This can be expressed as a percentage, so choice A is the correct answer. B is incorrect because standard deviation is not accounted for by the correlation coefficient. C is incorrect because statistical significance is not indicated by squaring the correlation coefficient. D is incorrect because correlation does not imply causation.
