Question

Quizplus · Accepted Answer

The numerical measure of linear association between two variables is the covariance, which measures the extent to which two variables vary together. The variance (A) and standard deviation (C) measure the variability of a single variable, while the coefficient of variation (D) is a measure of relative variability, not association.
