The best advice I could give to future students doing this project is to simply start right away and aim to get a sample of over 100 people. (We physically went to 109 people.) If you're wondering how you can get an A, besides a good write-up and correct equations at the end, getting a large sample shows how much effort you truly put into this project.
An interesting topic I'd like to see covered in a future statistics project would be: What factors go into the ideal college party? This could be something interesting. I'd love to see how the K community responds to something like that.
