Answer: B
Explanation:
Put the numbers in order from smallest to largest
the first smallest is your first dot at 13
That means D is out because that first dot is at 12
The last dot is 37 which means A is out because thats at 36
C is out because that at 38
B is your answer based on range, to figure out the box part, break up the numbers into quartiles(4 even groups). The middle numbers take the average or 27 and 27 so 27 is you middle box number
the left box is the average of 18 and 20 which is 19
the right box is the average of 31 and 33 which is 32
