There is a great deal of information (some scientific and some anecdotal) suggesting that exercise helps to lower stress levels. We want to see if this is true for our sample (our Opening Survey data). Use questions #13 (exercise) and #19 (stress) for the analysis (it is your job to determine IV and DV). Test at = .05. Stress group 1 M=4.66, SD=1.65, SE=.31, Stress group 2 M=4.69, SD=1.50, SE=.17, Levene statistic=1.87, df1=2, df2=101, p value =.160, ANOVA between groups sum of squares =5.36, df=2, mean square =2.68, F=1.13, p value=.329, within groups sum of squares=240.40, df=101, mean square=2.38, total=245.76, df=103 Explain the results of homogeneity of variance (if necessary), using p value for support. If it is not needed, write NA. c. Interpret the significance of the test statistic (using p value and real interpretation with IV and DV descriptors). d. Is a post hoc test needed for this analysis? If needed, interpret the results with p values as support. If post hoc is not needed, say that here and explain why. e. Calculate percentage of variance accounted for & Cohen's d i. Percentage of variance = ii. Cohen's d =
