Which of the following represents the mode in a data set?

The mode of a data set is defined as the value that appears most frequently. In other words, it is the number that occurs with the greatest frequency when all the entries in the data set are arranged. For instance, in a data set like {1, 2, 2, 3, 4}, the number 2 is the mode because it appears more often than any other number.

Understanding the mode is crucial, especially when analyzing data sets where certain values may dominate. This is particularly useful in fields such as statistics, economics, and various social sciences, where identifying the most common occurrences can provide insights into trends and behaviors.

By contrast, the median represents the middle value when all data points are sorted, and the average is calculated by summing all values and dividing by the number of entries. The highest value refers to the maximum in the data set, which is unrelated to frequency.
