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. Here are the number of games Gretzky played during each season: 79, 80, 80, 80, 74, 80, 80, 79, 64, 78, 73, 78, 74, 45, 81, 48, 80, 82, 82, 70 Calculate the standard deviation with all his games and without his two lowest seasons. Compare the data. Rounding to the nearest hundredth, the difference between the standard deviation with and with out the outliers is
