For an experiment involving three levels of factor A and three levels of factor B,with a sample of n = 8 in each treatment condition,what are the df values for the F-ratio for the AxB interaction?​
A)2, 63​
B)​4, 63
C)​6, 63
D)​8, 63

Quizplus · Accepted Answer

The degrees of freedom for the AxB interaction is calculated as (levels of A - 1) * (levels of B - 1), which is (3-1)*(3-1) = 4. The denominator df is calculated as total number of observations minus the number of groups, which is (3*3*8) - (3*3) = 63.
