Question

Quizplus · Accepted Answer

The coefficient of determination R² measures the proportion of the variation in the dependent variable that is explained by the independent variable(s). It ranges between 0 and 1, with 0 indicating that none of the variation in the dependent variable is explained by the independent variable(s), and 1 indicating that all of the variation is explained. Therefore, the best choice is (C) 0 and +1.
