Document Summary

To examine simple effects, we basically separate the two-way anova into multiple one- way anovas. The error term from the omnibus two-way anova is used. Consider an experiment concerning the driving ability of 2 different types of drivers (factor a): a1= inexperienced and a2 = experienced. These people will drive on one of 3 types of roads: (factor b: first class = b1, second class = b2, or dirt= b3, Under one of 2 different driving conditions- (factor c: day= c1 and night= c2 . This is a 2 x 3x 2= 12 cells. There are 4 participants per condition (cell) and the dependent variable is the number of steering corrections in a 1 km section of roadway. Main effects: factor a, factor b, factor c. First-order interactions: factor a x factor b, factor a x factor c, factor b x factor c. Second-order interactions: factor a x factor b x factor c.
