In the data set [4, 2, 4, 6, 2, 4, 7], what value occurs most often (the mode)?

• A. 2
• B. 6
• C. 7
• D. 4

Answer: (D)

The mode is the value that appears most often in a data set. In this list, 4 appears three times, while 2 appears twice and 6 and 7 each appear once. Since 4 occurs more frequently than any other number, it is the mode. There’s no tie for the highest frequency, so the mode is unique.
