Problem
A foodie blog has gathered data on the delivery times for four various restaurant delivery services (CHOMP, Uber Eats, DoorDash, Grubhub). Blog editor Auguste Gusteau has been analyzing the distribution of delivery times for each of these delivery companies and is contemplating how to visually compare the four delivery time distributions. Which of the following would you recommend?
a) Plotting all four delivery time distributions on a clustered column chart.
b) Using a collection of six charts each displaying a different pair of delivery time distributions with frequency polygons.
c) Using a trellis display arranging the four frequency polygons vertically.
d) Plotting all four delivery time distributions with frequency polygons.
