es for 11 rhesus monkeys. Factor B: Cardiovascular Reactivity Medium Low High M=1.36 | M=1.55 | M=1.82 T= 17 SS= 2.5455 | SS= 2.7273 | SS= 1.6364 Low T-15 T = 20 | TROWL = 52 2x2 237 Factor A: Stress | M=2.27 T=25 | M=1.73 T=19 M= 2.09 T = 23 High TRow2 67 : SS= 4.1818 | SS= 2.9091 | SS= 2.1818 Tcou = 34 Toou2 = 40 TOOL3 = 45 ou perform an ANOVA to test that there are no main effects of factor A, no main effects of factor B, and no interaction betwe actors A and B. Some of the results are presented in the following ANOVA table. ANOVA Table Source df MS Between treatments 6.2575 3.4091 12.64 Factor A Factor B A X B interaction 2.7613 1.3788 5.11 0.0908 Within treatments Total 22.4394 65 Work through the following steps to complete the preceding ANOVA table. main effect for factor A evaluates the mean differences between the levels of factor A. The main effect for factor B 1·The evaluates the mean differences and B in the ANOVA table. between the levels of factor B. Select the correct values for the sums of squares for factors A 2. Select the correct value for the within-treatments sum of squares in the ANOVA table.Explanation / Answer
1. SS between treatment = SS Factor A + SS Factor B
Given SS Factor A = 2.7613 and SS between = 6.2575. Therefore SS Factor B = 6.2575 - 2.7613 = 3.4962
SS Total = SS Factor A + SS Factor B + SS AxB + SS Within
2. Therefore SS Within = 22.4394 - 2.7613 - 3.4692 - 0.0908 = 16.0911
