Question

Quizplus · Accepted Answer

The most appropriate measure of the strength of the linear relationship between two numerical variables is the coefficient of correlation, which measures the direction and magnitude of the relationship. Scatter plot displays data but doesn't provide a numerical measure of the strength of the relationship. Slope and Y-intercept are measures of the linearity of the relationship but not the strength of the relationship.
