1. Do the data meet criteria for homogeneity of variance? Provide a rationale for your answer. When conducting a Leven’s test, you test the equal variances assumption. The p value of hours worked post treatment = 0.455. This shows that there is not any significant difference between the three groups’ variances. Therefore, the data does not meet the criteria for homogeneity of variance. 2. If calculating by hand draws the frequency distribution of the dependent variable, hours worked. What is the shape of the distribution? If using SPSS, what is the result of the Shapiro-Wilk test of normality for the dependent variable? The form of the distribution is uni-modal. The outcome of the Shapiro-Wilk test of normality for the dependent variable, (the # of hours worked post treatment with the statistic) = 0.934. The p value is larger than 0.05. This means that the occurrence of distribution ...
