In Chapter 2, Figure 2.15, I plotted three histograms corresponding to three different dependent variables in Everitt’s example of therapy for anorexia. Those data are available at www.uvm.edu/~dhowell/methods7/datafiles/fig2–15.dat. (The variable names are in the first line of the file.) Prepare Q-Q plots for corresponding to each of the plots in Figure 2.15.

Do the conclusions you would draw from that figure agree with the conclusions that you would draw from the Q-Q plots? (Note: None of these three distributions would fail the Kolmogorov-Smirnov test for normality, though no test of normality is very good with small sample sizes.)
