The multiple regression with two predictor variables is computed for a sample of n = 25 participants.What is the value for degrees of freedom for the unpredicted portion of the Y-score variance, MS_residual? A)2 B)3 C)22 D)23

Question

Quizplus · Accepted Answer

The degrees of freedom for the unpredicted portion of the Y-score variance, MSresidual, is equal to n - k - 1, where n is the sample size and k is the number of predictor variables. In this case, n = 25 and k = 2, so the degrees of freedom for MSresidual is 25 - 2 - 1 = 22.
