In the data set 3,7,7,2,9,7,5, which value occurs most often?

• A. 3
• B. 2
• C. 5
• D. 7

Answer: (D)

This problem is about the mode—the value that appears most frequently in a data set. To find it, count how many times each number shows up: 3 appears once, 7 appears three times, 2 appears once, 9 appears once, and 5 appears once. Since 7 occurs more times than any other value, it is the mode. Therefore, the value that occurs most often is 7.
