Two approaches, S (structured) and U (unstructured), to teaching a required undergraduate course in social research methods are to be compared with regard to their effects on student interest in social research. Students signing up for the course are classified as Type C (conforming) or Type I (independent) individuals according to personality test results. On a random basis, half of each type of student are assigned to section S of the course and half to section U. At the end of the course, scores are obtained on a scale of interest in social research and are analyzed using a two-factor analysis of variance.

The interest (in social research) scores are given below (normally far more cases would be used).
(a)Compute the variance estimates; complete the F tests at and ; and draw statistical conclusions. Show your results in a summary analysis of variance table
(b)Construct a table showing cell and marginal means. Considering the F-test results, which means would be of interest? Why?
(c)Construct a graph of the cell means. Draw final conclusions concerning the two treatment variables.
