The following data were obtained from a two‑factor independent-measures experiment.

                               B1             B2         

    A1

M = 22

T = 440

SS = 1540

M = 15

T = 300

SS = 1270

    n = 20 for all cells

    A2

M = 17

T = 340

SS = 1320

M = 18

T = 360

SS = 1266

        G = 1440

        N = 80

     ΣX2 = 31,836

- Following the steps of a hypothesis test, determine if there is a significant main effect of Factor A, a significant main effect of Factor B, and a significant AxB interaction. Use the .05 level of significance.

The following results are from an independent-measures, two factor study. Be careful that this is a 2x3 design. You are expected to extend your knowledge on 2x2 design to a 2x3 factorial design. The study: Consider an experiment designed to investigate the effectiveness of therapy for the treatment of anxiety or fear. Two kinds of therapy (systematic desensitization, counter conditioning) as well as a counseling-only control condition are included. The therapy and counseling programs have been conducted over a number...
