Explanation

This question tests ISEE Lower Level Mathematics Achievement skills: finding the mode of a data set. The mode is the number that appears most frequently in a set of values. It helps identify the most common occurrence in a data set. In this specific data set, the value 2 appears 4 times, which is more frequent than any other number. Choice B is correct because it accurately identifies 2 as the mode, demonstrating understanding of frequency. Choice A is incorrect because it represents the maximum value, which is a common mistake when students do not focus on frequency. To help students: Practice identifying the mode by counting occurrences of each number in a data set. Encourage checking each value's frequency and comparing to find the most common one. Watch for confusion between mode, mean, and median.
