Question

The box plots below show student grades on the most recent exam compared to overall grades in the class:
two box plots shown. The top one is labeled Class. Minimum at 70, Q1 at 74, median at 83, Q3 at 92, maximum at 100. The bottom box plot is labeled Exam. Minimum at 60, Q1 at 81, median at 87, Q3 at 91, maximum at 95.
Which of the following best describes the information about the medians?
The exam outlier at 60 makes the IQR narrower and the median higher.
The class data is more evenly spread, which pulls its median down.
The class median is lower than the exam median.
The class Q3 is higher than the exam Q3.

Answer 1

Thank you for asking this question. Here is your answer:

The answer is B.  

The class data is more evenly spread, which pulls its median down.

When the data is more evenly distributed over the range of 30, the result will either reflect in a lower or higher median. In this case, the class data is more evenly spread, which pulls it median down
