1. The following data are from a two-factor study, with n = 3 in each group, evaluating the effects of three treatment conditions on males and females.

Treatments Factor B

1 2 3

	M = 3	M = 6	M = 9
Male	T = 9	T = 18	T= 27	Tmale= 54
	SS = 14	SS = 26	SS = 8
Factor A				N= 18
Gender				G= 144
	M = 3	M = 12	M = 15	X2= 1608
Female	T = 9	T =36	T= 45
	SS = 8	SS = 14	SS = 26	Tfemale= 90

1. Use an ANOVA with = .05 for all tests to evaluate the significance of the main effects and the interaction. (12)
2. Complete Source Tablebelow. (3)
3. Calculate the effect size (²) for each main effect and the interaction (3)
