Outliers

In this section we will look at how to determine if any of our observations are outliers.  Outliers can affect many of our measures, but primarily our mean.  If there is an outlier, our mean gets pulled towards it.  For example, if a basketball player averages 8 points per game and scores 30 points in a game, his new average will rise considerably due to the outlying value.
