Giovanna has two possible driving routes to her new workplace, and she is having a hard time figuring out which is faster. The f
irst route is shorter, but usually has more traffic than the second route. She decided to conduct a small study. Over a period of 555 weeks, she used the first route in the first half of the week (Monday, Tuesday, and Wednesday), and the second route in the second half of the week (Thursday and Friday). Each day she recorded how long it took her to get to work, and by the end of the 555 weeks she calculated the average driving duration for each route. What type of statistical study did Giovanna use?
