@SmogDr original suggestion from book (place here to save idea after removing from branch)
Create a data fram from
df_mpg
that contains observations only for "Front-Wheel Drive" vehicles (one of thedrive
levels) that run on "Regular Gasoline" (afuel_type
level). With these data, create a series of boxplots showing combined fuel efficiency on the y-axis and year on the x-axis.
