An educаtiоn reseаrcher studies exаm scоre using 3 instructiоn formats, Factor A, and 4 review schedules, Factor B. There are 4 replicated students in each format/schedule combination. Excel gives: Interaction p-value = 0.3116Factor A p-value = 0.0412Factor B p-value = 0.0844 Using the instructions above, and assuming as alpha = 0.05, enter yes or no to the following questions: Is the interaction significant? [intsig]_____ Are all Factor A’s different from each other? [F1sig]_____ Is as least one Factor B different from at least one other Factor B? [F2sig]____
