Word Problems: When to Use Mean, Median, and Mode

A class of $20$ math students got the scores back on their most recent test. The scores were as follows:

$$62, 72, 62, 88, 93, 90, 86, 68, 99, 70, \\ 68, 60, 66, 99, 86, 71, 97, 70, 76, 63$$

If Abby got an $80$ on the test, is she above or below the average?
