If the coefficient of correlation r = +1, then the best-fit linear equation will actually be satisfied by all of the data points.

Question

Quizplus · Accepted Answer

A correlation coefficient of +1 represents a perfect positive linear relationship between two variables. This means that all data points would fall exactly on a straight line, and the best-fit linear equation would pass through every single point. Therefore, the statement is true.

If the Coefficient of Correlation R = +1, Then the Best-Fit
