What is a mode? I need a quick review... I understand it, I just want to know better.

The mode of a set of data is the value in the set that occurs most often.
3, 7, 9, 13, 18, 18, 24
In this set of numbers, the mode is 18, because 18 occurs the most times.

The mode is the number that appears most often in the set.
