If you have the set of numbers {2, 3, 4, 4, 5}, what is the mode?

The mode of a set of numbers is defined as the number that appears most frequently within that set. In this particular example, the set of numbers is {2, 3, 4, 4, 5}. To determine the mode, we can count the frequency of each number:

• The number 2 appears once.

• The number 3 also appears once.

• The number 4 appears twice, which is more frequent than any other number in the set.

• The number 5 appears once.

Since 4 appears more often than any other number in the set, it is the mode. A mode can be identified as the value that occurs with the highest frequency, and in this case, that value is clearly 4, as it occurs two times compared to the other numbers that only occur once. Thus, the mode of the set is correctly identified as 4.
