Question

Ten randomly selected people were asked to join a fitness group. Over the next two weeks, they were tested on how many push-ups they could do. The data shows the number of push-ups they did over the two weeks. From the first to the second week, what was the increase in the median number of push-ups?

Week 1: 5, 8, 10, 11, 6, 8, 9, 15, 5, 8
Week 2: 7, 9, 11, 12, 8, 10, 11, 18, 9, 10

Answer 1

The median in Week 1 is 8 (the 5th and 6th values are 8,8). The median in Week 2 is 10 (the 5th and 6th values are 10,10).

Increase = 10 − 8 = 2 push-ups.
