Male and female high school students reported how many hours they worked each week in summer jobs. The data is represented in the following box plots.
Box plots titled Males versus Females in Hours Worked Weekly during the Summer with horizontal axis labeled Hours worked per week ranges from 0 to 55. Males box plot with minimum approximately at 15 and maximum approximately at 35 has interquartile range approximately between 20 and 25 and median approximately at 22. Females box plot with minimum at 0 and maximum approximately at 50 has interquartile range approximately between 0 and 25 and median is approximately at 20.
Identify any values of data that may affect the statistical measures of center and spread.
The answer choices are:
A. The males worked less than the females, and the male median is close to Q1.
B. There are significant outliers at the high ends of both the males and females.
C. Both graphs are symmetrical, so IQR and median are appropriate measures of spread and center for both males and females.
D. There is a high data value that causes the data set for the females to be asymmetrical.
