Asked by Alexis

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 the first-, second-, and third-period classes are as follows:

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 second period and why?

A. Mean, because there are no outliers that affect the center

B.Median, because there is 1 outlier that affects the center

C.Interquartile range, because there is 1 outlier that affects the center

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

It's either A or D because there are no outliers. Does anybody know which one it is? I'm leaning more towards A. Mean, because there are no outliers that affect the center. Is this right?

Am I right? I just need a yes or a no??

Yes, Mean can also mean average. The average is the center of the group of numbers.
