- 3, 5, 7, 5, 5, 17, 8, 9, 11, 5, 3, 7
- -3, 0, 5, 8, 12, 4, 2, 1, 6
Calculate the mean and median for each set of numbers: - 12, 88, 89, 90
- 16, 17, 19, 20, 20, 98
- For which of the previous two questions was the medianless thanthe mean? What in the set of numbers caused
this? - For which of the previous two questions was the mediangreater thanthe mean? What in the set of numbers
caused this? - In each of the sets of numbers for problems 11 and 12, there is one number that could be considered anoutlier.
Which numbers do you think are the outliers and why? What would happen to the mean and median if you removed
the outliers?
