The following data give the numbers of driving citations received by 12 drivers randomly selected from a large city database: 4 8 0 3 1 16 4 1 48 1 37 9 i. Calculate the mean and median. ii. Does this data set contain any outlier(s)? If yes, drop the outlier(s) and recalculate the mean and median. Which of these measures changes by a greater value when you drop the outlier(s)? iii. Is the mean or the median a better summary measure for these data? Explain.
