The coefficient of correlation is the covariance divided by the standard deviation

Question

Quizplus · Accepted Answer

This statement is true. The formula for calculating the coefficient of correlation (also known as Pearson's correlation coefficient) is r = cov(X,Y) / (SD(X) * SD(Y)), where cov is the covariance and SD is the standard deviation. Therefore, the coefficient of correlation is indeed equal to the covariance divided by the standard deviation.
