Question

The degrees of freedom for factor A is the number of ______.A)  levels minus oneB)  levels for factor AC)  cases for factor AD)  cases for factor A minus one

Brendan Sammut · Accepted Answer

Final Answer : A, Explanation :  The degrees of freedom for factor A is calculated as the number of levels minus one, according to the principle of marginality in ANOVA. This is because the sum of squares for factor A is always constrained to equal the sum of squares between groups, which has (k-1) degrees of freedom, where k is the number of levels for factor A. Therefore, the degrees of freedom for factor A is also (k-1).

The degrees of freedom for factor A is the number of ______.

A) levels minus one
B) levels for factor A
C) cases for factor A
D) cases for factor A minus one
