Refer to the following set of data: B1 B2 A1 n = 5 M = 1 SS = 10 n = 5 M = 3 SS = 20 A2 n = 5 M = 1 SS = 10 n = 5 M = 1 SS = 10 For these data, what are the df values for the F-ratio for the A x B interaction? a. 3, 19 b. 1, 16 c. 1, 19 2. A two-factor experiment means that the experimental design includes _____. a. two independent variables b. exactly two separate groups of subjects c. two dependent variables d. not enough information 3. The results of a two-factor research study are organized in a matrix with the two levels of factor A for the rows and the three levels of factor B for the columns. The mean (M) and sum of squares (SS) are computed for each cell in the matrix. What value is obtained by adding all six of the SS values? a. SSbetween treatments b. SSwithin treatments c. SSAxB d. not enough information 4. For an experiment involving 3 levels of factor A and 3 levels of factor B, with a sample of n = 5 in each treatment condition, what are the df values for the F-ratio for the interaction? a. 3, 36 b. 0, 0 c. 4, 36 d. 2, 36

1. An experiment has two levels of independent variable A, three levels of independent variable B, 8 subjects per treatment combination (cell), how many subjects total were in the experiment? 2. An experiment has two levels of independent variable A, three levels of independent variable B, how many treatment combinations (cells) would there be?
