Giovanna has two possible driving routes to her new workplace, and she is having a hard time figuring out which is faster. The first route is shorter, but usually has more traffic than the second route. She decided to conduct a small study. Over a period of 5 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 5 weeks she calculated the average driving duration for each route. What type of statistical study did Giovanna use?

Experiment

Step-by-step explanation:

An observational study is a study where researchers simply collect data based on what is seen and heard and make inferences based on the data collected.

Whereas, Experimental studies are the ones where researchers introduce an intervention and study the effects.

Giovanna did not just collect data alone and make inferences based on the collected data, as is done during an observational study, but she studied the effects of the data that she collected by calculating the average driving duration for each route.

Hence we see that she conducted an Experimental study.
