Answer 2

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 7

The box plots show student grades on the most recent exam compared to overall grades in the class:

two bar graphs shown. The top one is labeled Class. Minimum at 74, Q1 at 78, median at 85, Q3 at 93, maximum at 98. The bottom bar graph is labeled Exam. Minimum at 81, Q1 at 85, median at 93, Q3 at 96, maximum at 99.

Which of the following best describes the information about the medians?

The exam median is only 1-2 points higher than the class median.
The exam median is much higher than the class median.
The additional scores in the second quartile for the exam data make the median higher.
The narrower range for the exam data causes the median to be higher.
