What number is the mode of the set: 2, 3, 5, 3, 8?

The mode of a set of numbers is defined as the number that appears most frequently within that set. In the given set of numbers: 2, 3, 5, 3, 8, you can count the occurrences of each number.

The number 2 appears once, the number 3 appears twice, the number 5 appears once, and the number 8 appears once. Since the number 3 appears more frequently than any other number in the set, it is classified as the mode.

Understanding the concept of mode is important since it helps in summarizing data sets and identifying trends, especially in statistics. In this case, only the number 3 has the highest frequency, confirming its status as the mode.
