1. What is your research question, and why did you choose this topic?
2. Has the highway gas mileage of compact cars increased during the last 5 years.
2. What type of study will you conduct—observational or experimental? Observational
3. Describe your study:
a. Who (or what population) will you study? 2014 and 2019 cars

I will study compact cars. I will also compare luxury and non luxury cars.
c. What role does randomization play in your study? Where will you use it? Please be specific. I got a list

number generator to select 25 from each list.
d. How will you choose your test subjects? using a random number generator
e. How and where will you collect your data? from the list I wrote down each randomly selected car's
highway gas mileage
4. Attach an organized chart or spreadsheet containing your data with all columns labeled and all data

5. If you use websites for your data collection, please note the URLs of the sites and describe the data
you will use below:
