First put the numbers in order: Samuel: 8 13 15 17 22 22 39 40 Sticker: 19 20 21 22 22 23 24 25 Second, pick the middle number. There are eight numbers and we have a pair of middle numbers: Samuel: 17 22 Sticker: 22 22 The median is the sum of both middle numbers divided by 2: Samuel: (17 + 22) $\div$ 2 = 39 $\div$ 2 = 19.5 Sticker: (22 + 22) $\div$ 2 = 44 $\div$ 2 = 22
