Explore the effect of outliers through an analysis of mean, median, and standard deviation. Your classes examine and compare these measures for two groups. They must make sense of a group that has a higher mean but lower median compared to a group with mean and median that is almost equal. Their examination should lead to a conclusion about spread and/or outliers.
