Quizplus · Accepted Answer

The coefficient of determination, or r-squared, is a measure of how well the data fits the regression line. It ranges from 0 to 1, with 1 indicating a perfect fit and 0 indicating no fit. Since the coefficient of determination is not negative, options A and B can be eliminated. Option D is also incorrect since it is negative. Therefore, the correct answer is C, which represents a perfect fit between the data and the regression line.
