Answer 19

well I'm not sure if IQR is the best choice. Not sure though.

But I think the best measurement for both of them is the standard deviation.

Answer 20

Answer 24

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:

two bar graphs shown. The top one is labeled Males. Minimum at 1, Q1 at 3, median at 10.5, Q3 at 24, maximum at 21. The bottom bar graph is labeled Females. Minimum at 0, Q1 at 15, median at 18, Q3 at 21, no maximum shown

Identify any values of data that might affect the statistical measures of spread and center.

The females worked more than the males, and the female Q3 equals the top of the range.
The spread and center are skewed due to the fourth quartile missing with the females.
There is a significant outlier at the low end for the females.
The males have a high outlier, and the females have a low outlier.

Answer 25
