One-way ANOVA using linear contrasts:

A statistics professor was interested in the difference various study methods would have on students' performance on the midterm exam. He established four treatment groups: a) no study at all, b) individual study for 1 hour per day, c) individual study for 3 hours per day, and d) 4 hour group study session once per week. The students' scores on the midterm exam are listed below. Analyze the data using linear contrasts to make the following comparisons:

Compute an F-statistic for each linear constrast and determine its significance. Also, state what questions each of these contrasts address. Please answer part A by hand and parts B and C using SPSS. Attach only the appropriate output (i.e., cut and paste only the relevant output tables needed to support your answers). Write a paragraph that summarizes your results.

No Study	Individual (1 hour)	Individual (3 hours)	Group Study
40	45	85	80
50	65	80	85
65	60	70	80
35	55	75	65
60	50	65	90

Compare group A to groups B, C, and D.
