The coefficient of determination R² is ________. A) sometimes negative B) always lower than adjusted R² ^C)usually higher than adjusted R² ^D)always equal to adjusted R²

Question

Quizplus · Accepted Answer

The coefficient of determination (R-squared) is always between 0 and 1, so it cannot be negative. The adjusted R-squared (RS1U1P12S1S1P0 S1U1P1) is used to account for the number of variables in a regression model and can be lower than the unadjusted R-squared. Therefore, option B is incorrect. The coefficient of determination (R-squared) is usually higher than the adjusted R-squared, so option C is correct. Option D is incorrect because the R-squared value and adjusted R-squared value are not always equal.
