To evaluate employee attitudes regarding a compressed workweek, an HR manager administered a questionnaire to two groups, one group using the usual 5/8 schedule and one group using the 4/10 schedule. The mean scores for both groups were the same, but the manager thinks the mean fails to show that the employees in the 4/10 group either love or despise the new schedule. What statistic should be compared to confirm this decision? median O mode standard deviation t-test or analysis of variance Choose 1 option
