Chapter 11, Problem 3.0E

Suppose a researcher conducts a two-factor study comparing two treatments (I and II) for college graduates versus adults with no college experience. The structure of the study is shown in the following matrix.

Treatment

I. College graduate..

II. No college.

a. If the results show that college graduates have higher scores than the no-college adults in treatment I and equivalent scores in treatment II. is it likely that there will be a main effect for the education factor? Is it likely that there will be an interaction?

b. If the results show that college graduates have higher scores than the no-college adults in treatment I and lower scores than the no-college adults in treatment II, is it likely that there will be a main effect for the education factor? Is it likely that there will be an interaction?
