Suppose three students were interested in studying the association between a person's political party (Democrat, Republican, Independent, or Other), and whether the person voted in the last election (Yes, No). Each of the three students selects a random sample of 40 students and recorded each student's political party and whether the student voted in the last election. The three Mean Group Diff statistics are: Mean Group Diff 1 = 0.12 Mean Group Diff 2 = 0.35 Mean Group Diff 3 = 0.27 Which Mean Group Diff statistic provides the strongest evidence against the null hypothesis
