Compare the standard deviation of a data set when removing an outlier. An outlier is an extreme value that is significantly less or more than the rest of the data. During his 20 season NHL career, Wayne Gretzky scored more points than anyone who played professional hockey. He accomplished this feat while playing fewer games than the previous record holder.
