A researcher conducts a one-factor experiment and shows that children are more afraid in dark rooms compared with well-lit rooms. Suppose you hypothesize that children will be less afraid of the dark room if a grown-up “checks” the room with them to show them it is safe. Complete the following assignment:

1. Construct a summary table that adds this second factor, checking, to test your hypothesis.

2. Enter hypothetical data in the table consistent with what your hypothesis predicts should occur. Identify whether you expect to observe a main effect or an interaction. Construct a graph from the table that displays the effect that is predicted by your hypothesis.
