Notes on Team Working Assignments\\
Thu Feb 10, 2011
\end{center}

Here is an updated schedule of Team Project Assignments, up through
Spring Break.

\section*{So far\ldots}

\begin{description}
\item[I.0] Teams Formed (Tue Jan 18)
\item[I.1] Propose Two Topics (Tue Jan 25)
\item[I.2] Revise proposals (Tue Feb 1)
\item[I.3] Choose Topic (Thu Feb 10).  Revise items A.--G. for the
  topic you've chosen, submit to brian@stat.cmu.edu

\end{description}


\section*{Upcoming\ldots}

The remaining Team Project Assignments will more or less follow the
``designing a sample survey'' outline from the beginning of the
semester.  {\em DATES AND DETAILS HAVE CHANGED; PLEASE READ BELOW.}
\begin{description}

\item[II.4] Target Pop, Sampling Plan, Sampling Frame, Nonresponse Plan
  (Tue Feb 15; \ul{one page}, emailed to brian@stat.cmu.edu) 
\begin{itemize}
\item Clearly define a \ul{\em target population} that you can reach in
  your survey
\item Clearly discuss your \ul{\em sampling plan}: How will you obtain
  a representative sample from the the target population  you
  defined?
\begin{description}
\item[If you are using] {\bf a sampling frame and random sampling
this should involve:}
\begin{itemize}
\item Clearly define a \ul{\em sampling frame}: a list of persons in
  the target population from which you can draw a random sample.
  Acceptable frames include: (a) list of email addresses from which
  you can draw an SRS without replacement; (b) set of phone numbers or
  prefixes that you can use for random-digit dialling (this is again
  an SRS without replacement); (c) list or map of blocks, addresses,
  or similar geographic information you can use to randomly select
  houses or businesses to approach; etc. 
\item Clearly discuss how you will use the sampling frame to obtain a
  representative sample.  Simple Random Sample (SRS)?  Stratified Sample?
  Clustered Sample? 
\end{itemize}
\item[If you are sampling] {\bf \ul{\bf not} using a frame and/or \ul{\bf not}
  using random sampling, this should involve:}
\begin{itemize}
\item Clearly describe your plan for obtaining a sample from your
  target population.  Acceptable plans include: (a) careful design of
  of times/dates/locations, where you will approach respondents; (b) a
  method of approaching or selecting respondents that removes
  respondent self-selection bias {\em and} interviewer selection bias;
  (c) a strong argument, based on verifiable facts and references,
  that this plan will have good coverage of your target population.
\item Claerly discuss how you will treat different locations or
  occasions for your observations: Will you throw all observations
  into one big group and analyze it like a SRS?  Will you treat
  different locations/occasions like a Stratified Sample?  Will you
  treat them like a Clustered Sample?
\end{itemize}
\end{description}
\item Clearly discuss how you will deal with \ul{\em nonresponse}:
\item What will you do about reminding or following-up nonresponders?
\item If you suspect your sample is not representative of the target
  population, what adjustments do you anticipate making?
\end{itemize}

\item[Team Working Agreements] (Tue Feb 15, in email to
  brian@stat.cmu.edu and {\bf on paper}.) [see
  separate handout -- online at \verb|http://www.stat.cmu.edu/~brian/303|]

\item[II.5a] Sampling Scheme \& Question Design (Thu Feb 24; email
  attachment to brian@stat.cmu.edu; I will only provide feedback if
  needed)
\begin{itemize}
\item Items K, L, M on the ``designing a sample survey''
  outline
\item Items K and M should be 1/2 page each.  Item L should be however
  long is needed.
\item For item M, please also include information on oversampling to
  compensate for nonresponse.  For example, if you anticipate a 25\%
  response rate and you want a sample size of 120, how many
  respondents should you approach?
  \begin{itemize}
    \item  I want every group to do this calculation for SRS without
      replacement -- even if you will not be using this exact method
      in your survey.
    \item If your group is planning to use a Stratified Sample or a
      Clustered Sample, we will discuss ways to adjust this sample
      size for these designs later in the semester.
    \item If your group is planning a non-framed or non-random sample,
      you will need to figure out how to (afford to) take a sample at
      least twice as large as the SRS w/o replacemen calculation.
  \end{itemize}
\end{itemize}
\item[II.5b] Pretest \& Revise Questions (Tue Mar 1; email
  brian@stat.cmu.edu ONLY part O.  I will provide feedback only if needed.)
\begin{itemize}
\item Items N, O on the ``designing a sample survey'' handout
\end{itemize}
\item[II.6] Final IRB \& Project Plan (Thu Mar 3; email attachments to
  brian@stat.cmu.edu);
\begin{itemize}
\item Final, full project proposal (items A-M on the
``designing a sample survey'' handout).
\begin{itemize}
\item From this proposal, anyone outside our class should be able to
  read and understand completely what you are proposing to do.
\end{itemize}
\item IRB form filled out completely, with all necessary attachments
  (see IRB information at \verb|http://www.stat.cmu.edu/~brian/303| or
  see CMU website \\ {\tt
    http://www.cmu.edu/osp/regulatory-compliance/human-subjects.html}).
% \end{itemize}
\item A draft informed consent statement for your survey.
\end{itemize}
Turn in all three to me, not CMU IRB.
% \item[EACH ASSIGNMENT ABOVE TURN IN BY EMAIL]~

\item[Peer Evaluation] (Thu Mar 3).  Please fill out and submit, on
  paper or in email, peer evaluations for your group.  For eample, if
  you have a five-person group, each person should submit 4 evaluation
  sheets: one for each other person in your group (for a total of 20
  sheets from your group!).  Peer evaluation sheets are available
  on-line at \verb|http://www.stat.cmu.edu/~brian/303|. \\

You will be graded {\em both} on submitting a full set of peer
evaluations for your group {\em and} what other members of your group
say about you in their peer evaluations of you.
