Simple Effects
• The effect of one factor at one level on the other factor.– Use to “tease apart” a significant interaction
• You wonder if college major has an effect on class attendance for just females?
• You wonder if male and female psychology students differ in their class attendance?

Simple Effects
• Why not just do 5 new analyses– 2 ANOVAs– 3 Independent Samples t-tests
• You will lose df!
• Type I error problem still exists

Simple Effects
• SS Major at Female
– Represents the SS deviations of the treatment means around the Female mean
– Its multiplied by n to give an estimate of the population variance (Central limit theorem)
– Same formula as SSbetween in the one-way
