Question

Celine is training to run a marathon. During her training, she kept track of how much time

she spent running on the treadmill inside and on a trail outside each week. These box plots
show the results.
Where was there more variation in the amount of time Celine spent running?

Answer 1

There was more variation in her time spent running outside.

Explanation:

This is because the range for running outside is larger.

To find range you subtract the largest number in the data by the smallest.

RANGE FOR INSIDE: 150 - 25 = 125

RANGE FOR OUTSIDE: 200 - 50 = 150

Since the range is larger for the time outside spent running, there is more variation.
