Measure central tendency, variability, skewness and kurtosis, Basic Statistics

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.
