The data {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7} has:
Median: Thee are 16 data items, so the median is the mean average of the middle two, ie the 8th and 9th numbers: median is (3 + 3) / 2 = 3
Mean: (1 + 1 + 2 + 2 + 2 + 3 + 3 + 3 + 3 + 4 + 4 + 4 + 5 + 5 + 6 + 7) ÷ 16 = 55 ÷ 16 = 37/16 = 3.4375
