What is the mode of the following data set: 1, 2, 2, 3, 4?

To determine the mode of a data set, you identify the value that occurs most frequently. In the given set of numbers—1, 2, 2, 3, 4—you can count the occurrences of each number. The number 1 appears once, the number 2 appears twice, the number 3 appears once, and the number 4 also appears once. Since the number 2 appears more times than any other number in the set, it is the mode. The mode is important because it can indicate the most common value in a data set, which can be useful in various statistical analyses. Thus, in this case, the mode is indeed 2, confirming that it is the correct answer.
