12.5 Solution: Check Your Understanding

We conducted a 2x2 factorial ANOVA predicting BAM scores from gender (man, woman) and treatment condition (treatment, control). There was a significant main effect of treatment condition, F(1, 236) = 57.35, p < .001, η_p² = .20. Participants in the treatment condition (M = 43.22, SD = 10.19) had lower BAM scores compared to participants in the control condition (M = 52.02, SD = 7.59). There was no significant main effect of gender, F(1, 236) = 0.01, p = .94, η_p² < .001. There was no significant interaction between treatment condition and gender, F(1, 236) = 1.36, p = .25, η_p² = .01.
