When given the numbers 4, 4, 5, 5, 5, what is the mode?

The mode of a set of numbers is defined as the value that appears most frequently. In the given set of numbers—4, 4, 5, 5, 5—each number occurs a certain number of times. The number 4 appears twice, while the number 5 appears three times. Since 5 has the highest frequency of occurrence in this list, it is identified as the mode. Understanding this concept is crucial, as identifying the mode helps in analyzing data sets in various mathematical and statistical contexts.
