The degrees of freedom within groups (dfWG) can be calculated using the formula dfWG = NAB - AB, where N is the total number of observations, A is the number of levels in factor A, and B is the number of levels in factor B. Given NAB = 10 (total observations for each combination of levels of A and B), A = 3, and B = 2, the total number of observations N = 10 * 3 * 2 = 60. Therefore, dfWG = 60 - (3*2) = 60 - 6 = 54.
