The graph below gives the current GPA of every one of the 389 students at County High School.

Which of these values of the GPA for the students portrayed in the graph is between 2 and 3?

Correct Answer: D

Explanation:

(D) Since there is a large cluster of students with GPAs between 2 and 3, it is possible to estimate that the mean and median will fall in that range. The most frequent value, the mode, will also be in that range since the greatest number of students with a particular GPA is between 2 and 3.
