A two-factor ANOVA compares two different treatment conditions (Factor A) for males and females (Factor B). In this study, the males have an average score of 15 in the first treatment and an average of 30 in the second. The females average 40 in the first treatment and 10 in the second. For this study, there is no interaction.
