The exam scores of 5 dental students are 64, 56, 48, 66, and 66. What are the median and the mean?
Show answer and explanation
Correct answer: B. 64, 60
Sorted: 48, 56, 64, 66, 66 — the median (middle value) is 64. The mean is (48+56+64+66+66)/5 = 300/5 = 60. So median = 64 and mean = 60, matching option B.
