The Department of Education wishes to investigate if the average GPA of MBA students varies with the size of university (small, medium and large) and type of MBA (regular, professional and executive) program. In order to investigate this issue, the Department of Education randomly picked 4 universities for each of the 9 university type-MBA program combinations and recorded the average GPA of the MBA students. The data is in GPA.sav.
Does the mean GPA differ for the three sizes of the university? Does the mean GPA differ for the three types of MBA programs? Does the MBA type affect the mean GPA of the university size? State the appropriate hypothesis, run the appropriate statistical test and provide interpretation. Which combination of university size and MBA program type results in the lowest average GPA?
If regression is required, please provide the multi comparison table.
