A. Mean, because there are no outliers that affect the center
Am I right? I just need a yes or a no??
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?
