Please find attached my feedback on your revised/extended project
proposals.  

For II.4 Turn in a one-paragraph reminder of your project proposal,
followed by the following sections.  

Please consult my comments on I.3, as well as the more detailed
instructions in the "UPDATED PROJECT SCHEDULE" posted at
http://www.stat.cmu.edu/~brian/303, for more details.

K. SAMPLING SCHEME: Decide on a sampling scheme (e.g., SRS, Stratified
random sample, etc.) and explain why you chose it.

L. DRAFT QUESTIONNAIRE: Write a questionnaire with 20--30
questions. Up to approximately 1/3 of these can be background or
demographic questions and the rest should be directly related to the
research questions you will try to answer with your survey.

   NOTE: If your survey involves observations instead of asking people
questions, then instead you should carefully describe your observation
protocol.  That is, list 20--30 things you will always look for when
observing each unit in your survey.

M. SAMPLE SIZE: Give some idea of the sample size you will require and
how you arrived at this number (talk about the margin of error for
inferences you want to make).

Remember, Project Assignment II.4 is due Fri at midnight on Blackboard.
