For future students -
I think the most important thing for this project is for students to create their survey and hand it out as soon as possible. This leaves more time for the student(s) doing the project to toy around with the data and try to decipher as much useful information as they can out of their data. In particular, regression is an important device that students need practice at in order to refine their skills regarding analyzing regressions. The more time students leave between the time they finish the survey and the actual due date for the project, the less stressful (and more enjoyable) the project will be.
