  • Textbook: Sampling: Design and Analysis, Sharon Lohr, 1999 Duxbury.
  • References:   (1) Sampling Techniques (third edition), William G. Cochran, 1977, John Wiley and Sons; (2) Elementary survey sampling (sixth edition), Richard L. Scheaffer, William Mendenhall III, and R. Lyman Ott, 2006, Duxbury.
  • Website: The website for this course will be available around the middle of the first week of lecture at Follow the directions all the way to find Stat 344. Here you will be able to download problem sets, solution sets and any additional material. Announcements and lab handouts will also be made available here.
  • Course Description: ntroduction to sampling from large finite populations. This includes various sampling schemes (Simple Random Sampling, Stratified Sampling, Cluster Sampling, Systematic Sampling, etc.), estimation methods (ratio and regression estimators), some topics from unequal probability sampling, nonresponse and if time permits the jackknife and bootstrap methods. Thus we will cover most of chapters 1 through 5 in the text as well as parts of chapters 6, 8 and 9.The TA for this course is Chen Xu ( He will lead the labs on Mon 16:00--17:00, Wed 15:00--16:00 and Fri 15:00--16:00 which will all be held in MSRC. The purpose of the labs are three-fold. First to revisit material seen in class, second to learn how to use the software which will be required and/or useful for the assignments and third to work on assignments. We will use the program SURVEY, described in Appendix A of the text, throughout this course (mostly for assignments). In addition, R will be taught in the labs. You are free to use any software in solving assignments. However, if you choose to use another software, such as Microsoft Excel, then you will be responsible to ensure your solutions can be understood by the TA.  TA office hours will be every Wednesday 4-5pm and Thursday 1:30-2:30 pm, in LSK 312.
  • Evaluation: There will be 6 assignments, one midterm exam and a comprehensive final exam. The assignments will be worth 25% of the final grade, the midterm 25% and the final exam 50%. However, if your grade for the final exam is higher than that of the midterm, the midterm will be worth 5% and the final exam will be worth 70%. The final exam will cover the entire course, but concentrate more on post-midterm material. For both exams you will be allowed to bring a two sided, hand written formula sheet (8.5 by 11 inch paper). Assignments will be on a roughly bi-weekly basis and the midterm will take place in class around middle of February.

    It is understood and, in fact, encouraged, that students discuss the assignments. It’s fine to work together, but the final product must be done independently. Plagiarism is an academic crime and will be dealt with accordingly. It is better for everyone not to hand in an assignment rather than hand in plagiarized work.

R can be downloaded from .
