The following data were from a two-factor between-subject study using 5 subjects in each treatment condition.

1. On the basis draw an interaction graph using the data of this experiment. Just by eyeballing the graph, is there an interaction effect? By eyeballing the table, is there a main effect for factor A? What about factor B?
2. Please attempt to do two-way ANOVA to test the main effects and interaction effect. Use the .05 level of significance.
3. Explain the main and interaction results to your grandma.
4. Compute the effect size for each main effect and the interaction.

Factor B B1 B2 M=3 M=5 Factor A A1 SS=80 SS=90 M=1 M=11 A2 SS=70 SS=80
