A community college uses three different methods of instruction (face-to-face, online, and hybrid) in its classes. The president of the college would like to know if there is a difference in student outcomes for the three methods. To test the question, a random sample of 24 students (8 from each method of instruction) was selected and their scores from a common final exam were compared using ANOVA.   Question: In an effort to reduce administrative and staffing complexity, the college is considering dropping hybrid courses and just offering face-to-face and online classes. Based on the result of your ANOVA test in the previous question, would the college be justified in eliminating hybrid courses, or does your test indicate follow-up investigation of the three instructional methods is needed? Briefly explain your answer, from a statistical perspective.
