A commuter has a choice of two routes for his morning drive to work. in an effort to determine the best route, he collects data on his drive time for each route. if he is interested in a route with a predictable drive time, which route should he choose and why?

Having carefully considered the preference of the commuter which is "a route with a predictable drive time", he should pick Rural Roads route. And this is because this route has a lesser IQR (interquartile range), which shows a smaller spread and more consistent times.
