In the data set {2, 4, 4, 6, 6, 6, 8}, what is the mode?

• A. 2
• B. 8
• C. 4
• D. 6

Answer: (D)

The mode is the value that appears most often in a data set. In this set, the number 6 appears three times, while 4 appears twice and 2 and 8 appear once each. Since 6 occurs more frequently than any other number, it is the mode. It’s the unique mode here because no other value shares that highest frequency.
