Compare the box-and-whisker plots below that shows the fuel efficiencies for cars vs trucks. On average, do cars or trucks have better fuel efficiency (miles per gallon)?
The number line has fuel efficiency values from 10 to 54 miles per gallon in increments of 2.
For cars the approximate values are as follows:
Minimum: 15
First Quartile: 18
Median: 20
Third Quartile: 22
Maximum: 50
For trucks the approximate values are as follows:
Minimum: 12
First Quartile: 14
Median: 15
Third Quartile: 16
Maximum: 21
