Final answer:
The distribution of scores on the exam is spread out, with a wide range of scores including both low and high scores.

The minimum score is 30, the first quartile is 32, the median is 50, the third quartile is 78, and the maximum score is 99. This suggests that there is a wide range of scores, including both low and high scores.
