As far as advice would go, I suggest staying on top of your surveying. When you go throughout the quarter meeting deadlines for this project you can easily be fooled into a false sense of ease when the next deadline is not for two weeks. Do not be fooled that you will need all of this time to not only set up your surveys but to also put the data into excel. Another thing, do not try and figure out excel all on your own. Work in teams and if confused about excel ask the professor. They are more than willing to help and this will save you a lot of time in regards to calculations. Excel is a wonderful tool when doing this project and you should try and use it to the best of your advantage.
I would suggest the topic of looking at college students that stay up past 1:30 am-2 am on a regular basis. I think this could be very interesting because you could find out how priorities rank in their day and see what kind of results stem from these different sleeping patterns. Then try and relate these sleeping patterns to what kind of jobs they might want to get once graduated. It could lead to a fun and interesting project looking at what area of academics has what trends.
