What is the range (max minus min) of the data set [3, 9, 2, 14, 7]?

• A. 12
• B. 11
• C. 13
• D. 14

Answer: (A)

Range is how far the data spread out, found by subtracting the smallest value from the largest value. In this set, the smallest number is 2 and the largest is 14. So the range is 14 minus 2, which equals 12. The other numbers don’t change this because they lie between those two endpoints.
