Quizplus · Accepted Answer

In a two-factor study, the degrees of freedom for between treatments is calculated as (levels of factor A - 1) + (levels of factor B - 1) + (levels of factor A - 1) * (levels of factor B - 1). For 2 levels of factor A and 3 levels of factor B, it is (2-1) + (3-1) + (2-1)*(3-1) = 1 + 2 + 1*2 = 5.
