Question

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

Two box plots are shown. The top one is labeled Class. Minimum at 68, Q1 at 71, median at 84, Q3 at 89, maximum at 100. The bottom box plot is labeled Exam. Minimum at 55, Q1 at 76, median at 85, Q3 at 94, maximum at 100.

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

The class and exam medians are almost the same.
The exam median is much higher than the class median.
The class and exam Q3 are the same, but the exam has the lowest median.
The low outlier on exams pulls the median lower.

Answer 1

First one:
