A recent study indicates that simply giving college students a pedometer can result in increased walking (Jackson & Howton, 2008). Students were given pedometers for a 12- week period, and asked to record the average number of steps per day during weeks 1, 6, and 12. The following data are similar to the results obtained in the study. Use a repeatedmeasures ANOVA with α=.05 to determine whether the mean number of steps changes significantly from one week to another. (do all 4 steps of conducting a hypothesis test!!): If there is a significant different, calculate the percent of variance that is explained by treatment differences (??2) and conduct both Tukey and Scheffe post hoc tests.
