A large school district has several middle schools (MS). Three schools were randomly chosen, and four classes were selected from each. The numbers of pupils in each class are shown here. Is there sufficient evidence that the mean number of students per class differs among schools? Please calculate the following: MS 1 MS 2 MS 3 21 28 25 25 22 20 19 25 23 17 30 22 Which Middle School (MS) had the largest average? Type only the number that corresponds with the following: 1 = MS 1 2 = MS 2 3 = MS 3 What is the critical value? What is your MSW? What is the f-ratio? Do you reject or fail to reject H0 (reject/fail)? Do you calculate effect size based on decision? (yes/no) Assuming your f-ratio was significant, what is the strength of association? Type only the number that corresponds with the following: 1 = Small 2 = Medium 3 = Large Do you calculate post-hoc Tukey HSD based on decision? (true/false)
