## Check the descriptive statistics, histograms, stem-and-leaf plots,

Check the descriptive statistics, histograms, stem-and-leaf plots, and the tests for normality that you obtained from your analyses (see box to check in "Plots" when using Explore to analyze descriptive statistics of your data). Considering the skewness and kurtosis values, as well as the Shapiro-Wilk's results (preferred for small sample sizes),

Did the distribution of scores on either of the dependent variables violate the assumption of normality?
