Question

Quizplus · Accepted Answer

The coefficient of determination is used to evaluate the goodness of fit, which makes option D the correct one. Option A is incorrect because the coefficient of determination takes values between 0 to +1, not -1 to +1. Option B is incorrect because the coefficient of determination is actually equal to 1 for a perfect fit, not zero. Option C is incorrect because the coefficient of determination is not equal to negative one for the poorest fit, it can only take values between 0 to +1.
