The adjusted R² statistic A) is equal to the value of unadjusted R² B) adjusts R² for the degrees of freedom in the multiple regression model C) accounts for the parameters in the multiple regression model D) is always greater than R² unadjusted

Question

Quizplus · Accepted Answer

The adjusted R² statistic adjusts for the degrees of freedom in the multiple regression model by taking into account the number of predictor variables included in the model. It is not equal to the unadjusted R² statistic, and may be greater or less than the unadjusted value depending on the number and importance of the predictor variables included. It also accounts for the parameters in the multiple regression model. Therefore, B is the best choice.
