(a) Test the A term, assuming all factors are fixed.

(b) Suppose Crepresents randomly chosen items. How will your analysis (F tests, EMS) differ from that when all three factors have fixed effects? Again, test the A effect.

(c) Without doing the calculations, set up the F test for B and AB, again assuming the effects of C are random. Several different measures are available in the Wiley file in the Wiley Voss folder. Of these, the SVT (sentence verification) and IVT (inference verification) are on the same scale, and differences between the two tap the difference between memory for explicitly stated information and the inferences drawn from the material studied. We might wish to see if these differences are affected by the format and text manipulations.

(a) Plot the cell means and describe the resulting pattern. What effects are suggested?

(b) Perform an ANOVA with format and text as between-subjects variables and test (SVT vs. IVT) as the within-subjects variable. Discuss the results, relating your discussion to the plot of the means..
