Mean

Median

Mode

• A. I only
• B. II only
• C. I and II only
• D. I, II, and III

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.
