The box plots below show the average gas mileage, in miles per gallon, of the cars sold at a dealership in June and in December.

Gas Mileage of Cars Sold in June
2 box plots. The number line goes from 14 to 34. For cars sold in June, the whiskers range from 21 to 33, and the box ranges from 22 to 29. A line divides the box at 24. For Cars sold in December, the whiskers range from 14 to 26, and the box ranges from 18 to 21. A line divides the box at 19.

33 minus 21 = 12
29 minus 22 = 7
Sold in December
19
26 minus 14 = 12
21 minus 16 = 5
