Abstract:
|
Health researchers must master basic principles and methods for critiquing and producing health research literature efficiently; thus, they need to understand various methods of sampling. Two recent articles in the February 2007 issue of The American Statistician, one by Alf and Lohr, the other by Strasak et al, can motivate discussion about how to introduce these concepts to students in the health sciences. Al and Lohr review the treatment of sampling assumptions for confidence intervals and hypothesis tests in several texts. They identify strengths and flaws and propose promising approaches to teaching simple random sampling, cluster sampling and confidence intervals. Strasak et al. identify related errors that show up in medical research articles. They provide a quality improvement checklist for statistical evaluation of medical manuscripts.
