He accomplished this amazing feat while playing in 280 fewer games than Gordie Howe, the previous record holder. Here are the total number of points scored by Gretzky during each season, in order, from the 1979-80 season to the 1998-99 season: 137 164 212 196 205 208 215 183 149 168 142 163 121 65 130 48 102 97 90 62 Create a stem and Leaf for these data. Describe the shape and any unusual features of the distribution. What might explain it? Calculate the mean and median for this data. Would you use the median or the mean to describe the centre of this distribution? Why?

Explanation / Answer

a)

b) The shape is left skewed. The distribution of the data is more towards right. Hence Left skewed or Negatively Skewed.

c) mean= 142.85

     Median = 145.5

d) Since the distribution is Skewed Hence we will go with median to describe the distribution.
