If there is no linear relationship between two variables x and y,the coefficient of determination must be −1.0.

Question

Quizplus · Accepted Answer

The coefficient of determination, also known as R-squared, measures the amount of variance in one variable (y) that can be explained by another variable (x) using a linear regression model. If there is no linear relationship between x and y, the coefficient of determination will be 0, not -1. A negative value of R-squared is not possible.
