In Exercise 12.18 it would not have made much of a difference whether we combined the data across the three intervals or not. Under what conditions would you expect that it would make a big difference?

Use any statistical package to apply the Tukey and Scheffé procedures to the data from Intronis-Collison and McGaugh (1986), described in the exercises for Chapter 11 (page 366). Do these analyses for both Epineq.dat and Epinuneq.dat, which are on the book’s Web site? Do not combine across the levels of the interval variable.
