Dr. Cal is teaching "Introduction to Psychology" and "Introduction to Statistics." He assigned one group of students to study with "active learning strategies" and one group of students to study with "passive learning strategies" so that half the students in each class studied using one of the two strategies. He then compared final grades for all students.

• Compute the analysis of variance summary table. (You may include an SPSS or other program output table; 10 points)
• Was there a main effect of study strategy? How do you know (report the appropriate info)? (2 points)
• Was there a main effect of class type? How do you know (report the appropriate info)? (2 points)
• Was there an interaction? How do you know (report the appropriate info)? (2 points)
• Explain your overall conclusion of the ANOVA in your own words so that someone without statistics training could understand the results. (4 points)
