1. A researcher is comparing two middle school 7th grade classes. One class at one school has participated in an arts program (involving putting on a musical play) which emphasized training in group cooperation skills. The class at the other school also put on the same musical play, but did not participate in the cooperation skills training. One month after each group performed the play, they took a paper and pencil social skills test and the scores are shown below. Compare the two groups in terms of measures central tendency, variability, skewness, and kurtosis. What do these measures tell you about the scores in the two groups?
