Answer
The median for Samuel is 19.5 and for Sticker is 22 .
Work Step by Step
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
