EPID600 (Fall 2009) module on
Selection bias


Instructions:
  1. Read: Aschengrau and Seage, ch. 10 - Bias

  2. Read the lecture slides and attend the lecture (if you cannot attend the lecture, the slides have verbatim speaker notes; there are also recorded audio tutorials, but these are not as up-to-date as the speaker notes).

  3. Read Peterman TA. (1995). Can we get people to participate in a study of sexual behavior? Sexually Transmitted Diseases 22, 164-168. (UNC-CH: full text))
        and
     J. Frantzen, T.G.W. Speel, L.A. Kiemeney and E.J.H. Meuleman. Cardiovascular Risk Among Men Seeking Help for Erectile Dysfunction. Annals of Epidemiology 2006 (February); 16(2):85-90. (abstract, UNC-CH: full text)

  4. Answer (all of) the case study questions. Write succinct answers that include a brief explanation or statement of support.

  5. (Optional, but earns credit) Submit the answers to the starred case study questions (numbers 1, 3, 4, 8, and 12 - see the class schedule for due date).

  6. Discuss the answers to (all of) the case study questions with your small group.

  7. Agree on the answers (including the brief explanation or statement of support), so the facilitator can submit the group’s consensus answers (for all questions) by the date indicated in the class schedule.
