Question: 293
12. The box-and-whisker plot below shows the number of days without sunlight in a remote village in northern Alaska during winter last year.
What is the range of the data?
- A. 30
- B. 45
- C. 55
- D. 70
Correct Answer: B
Explanation:
B
The vertical lines at either end of the box-and-whisker graph represent the lowest and highest data points. (The vertical line in the middle of the two boxes represents the median.) As range is calculated by subtracting the lowest value from the highest value, the range here is 70 – 25 = 45.
