(06.03 lc) 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
