A survey was taken of students in math classes to find out how many hours per day students spend on social media. The survey results for
period classes are as follows:
the first-, second-, and third-

First period: 2, 4, 3, 1, 0, 2, 1, 3, 1, 4, 9, 2, 4, 3, 0

Second period: 3, 2, 3, 1, 3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2

Third period: 4, 5, 3, 4, 2, 3, 4, 1, 8, 2, 3, 1, 0, 2, 1, 3

Which is the best
measure of center for third period, and why?

Interquartile range, because there is one outlier that affects the center

Standard deviation, because there are no outliers that affect the center

Mean, because there are no outliers that affect the center

Median, because there is one outlier that affects the center
