For a two-factor study with two levels of factor A,2 levels of factor B,and a separate sample of n = 10 participants in each treatment condition,the two means for level A1 are 4 and 1,and the two means for level A2 are 3 and 2.For these data,what is the SS value for factor A (SS_A)? A)0 B)50 C)125 D)250

The SS value for factor A is calculated based on the differences between the group means and the overall mean. In this case, the means for A1 are 4 and 1, and for A2 are 3 and 2. The overall mean is (4+1+3+2)/4 = 2.5. Since the means for each level of factor A (2.5 for A1 and 2.5 for A2) are the same as the overall mean, the SS for factor A is 0, indicating no variability due to factor A alone.
