What main effects and interaction could you test with the design you developed for Question 1? Are you predicting that you will obtain an interaction?
Question 1
Build on the design you created in Question 2 to test the hypothesis that the effects of watching violent TV shows will be greater for boys than for girls. (What kind of design is this?)
Question 2
Design a randomized groups experiment to test the hypothesis that children who watch an hour-long violent television show subsequently play in a more aggressive fashion than children who watch a nonviolent TV show or who watch no show whatsoever.
