Team C: How to improve our oncampus parking system? Silvia Manolache, Nicholas Thieme, Shu Wang, Yijia Zhou GENERAL COMMENTS: * Great that you pre-stratified. This almost always improves results. * Because you used just 2 pre-strata, you may find you need to post-stratify (within each pre-stratum separately) also. See handout "post-stratification challenges" toward the end for strategies to do this. * The issue of when and how to introduce the raffle is interesting (and whether to offer it to those who have already responded). I'll be interested to see how this plays out (for you, and as advice to future 303 groups). * You had a multistage sampling method for Cbook which I don't quite remember. Please describe it in your written report... I recall thinking it was interesting and a good idea. I am not assigning scores to parts of the presentation below since I will just give you all 100s. GRADING SCHEME FOR PRESENTATIONS Introduction: /10 What’s it about? Research Question & Motivation Questionnaire, or at least a couple sample questions from it Body: /50 Describe the work you have done so far How sample was selected... Any advice for future 303 students? How survey was set up and respondents contacted Glitches? How did you fix ‘em? What is the nonresponse or refusal rate so far? How will you decrease it? What are the distinguishing features of nonresponders/refusers? Successes? Tell us. Conclusion: /10 Future work – what’s left to do? When will you / did you cut off data collection? What post-processing and/or analyses will you perform? (nonresponse, poststratification, answering your research questions, etc.) Anything else? Individuals: /30 Know what you're talking about. Sound practiced, not rushed. At least 2 real slides per person Each person will get a score which is the sum of the above (so, 70 pts from group preparation of slides, 30 pts for individual presentation), except that un-excused no-shows will get 0.
