Below are the cell means of three experiments. For each, compute the main effect means and decide whether there appears to be an effect of A, B, and/or A x B.

Study 1

	A1	A2
B1	2	4
B2	12	14

Study 2

	A1	A2
B1	10	5
B2	5	10

Study 3

	A1	A2
B1	8	14
B2	8	2

If you label the X axis with factor A and graph the cell means, what pattern will you see for each interaction?
