For a sample of 65 students analyzing 3 predictor variables, what is the degrees of freedom for the denominator of the F-ratio equation?
A) 61
B) 63
C) 64
D) 65

Question

Quizplus · Accepted Answer

The degrees of freedom for the denominator of the F-ratio equation in a multiple regression analysis is calculated as the total number of observations minus the number of predictor variables minus 1. Therefore, for 65 students (observations) and 3 predictor variables, the degrees of freedom would be 65 - 3 - 1 = 61.
