alleryStart learning →A box plot runs from a smallest value of 20 to a largest value of 68. What is the range?
A88
B48
C34
D44
Answer & Solution
Correct answer: B. 48
1. The range is the largest data value minus the smallest.
2. Here that is 68 minus 20.
3. So the range is 48.
4. Adding the two ends gives 88, and averaging them gives 44, so neither of those is the range.
