\begin{center}
\bf 36-303: Sampling, Surveys \& Society\\
HW03: Hand in in-class Thursday, Mar 25, 2010
\end{center}

\noindent\ul{\em Reminders:}
\begin{itemize}
\item Everyone has an approved II.6 (final survey proposal and IRB
  application) so you should go ahead and collect your data.
\item Rough schedule of project due dates for remainder of term:
\begin{description}
\item[Meeting of Minds] Poster submission deadline Apr 1.
\item[III.7] Progress Report on Data Collection \& Analysis (Apr 1, 6
  \& 8) [20-min Powerpoint presentation in class]

\item[III.8] Rough Draft of Final Report (Due Apr 8)
              [a single pdf or doc file emailed to me]

\item[``Final'' Midterm Exam] Tues Apr 13

\item[III.9] Final presentations (Apr 22, 27 \& 29); \\
             Final Report Due (Due Fri Apr 20)
              [a single pdf or doc file emailed to me]
\end{description}
\item Reading:
\begin{itemize}
\item Review all of Groves Ch 4: Sample Design \& Sampling Error
\item Review Groves Ch 6: Nonresponse
\item New: Groves Ch 10: Post-Survey Processing
\item If you have Lohr, you could see some gory details in Ch 2 (SRS),
  Ch 4 (Stratified Sampling) and Ch 5 (Cluster Sampling)
\end{itemize}

\end{itemize}

\noindent\ul{\em Exercises to Turn In (there are 5 exercises):}
\begin{enumerate}

% \item Groves, Ch 4, pp. 133--134, \#7 % why a stratum \neq a population

\item Groves, Ch 4, pp. 134--135, \#8 % std stratum calculations of mean,
                                % var

\item Groves, Ch 6, pp. 196--197, \#2 % computing nonresponse err/bias

% \item Groves, Ch 6, p. 198, \#5 % difference between nonresp rate vs
%                                 % bias

\item Groves, Ch 6, p. 199, \#9 % methods of incr resp, and where they
                                % might fail

\item Groves, Ch 10, pp. 342--343 \#3. The weighted mean wanted in
  part (a) uses the ``base weights'' in the formula at the top of
  p. 324.  Refer to sections 10.5.1 and 10.5.2 to answer the
  qualitative part of part (a).
  % design weights and post strat weights

\item Groves, Ch 10, p. 343, \#6.  Make sure you give at least 2
  strengths and 2 weaknesses for each method (which might be the same
  or might be different between methods), and directly compare the
  strengths and weaknesses.

\end{enumerate}
