Merchandise Description

William A. Oleckno (2002)

This comprehensive, user-friendly, and academically sound textbook covers the basic principles and methods of epidemiology in such a way that will appeal to a broad range of undergraduate and graduate students in the health professions. Beyond its clear, concise writing, Essential Epidemiology offers unique pedagogic aids, such as an algorithm to help students identify epidemiologic study designs, a discussion of problems students typically encounter in calculating and interpreting incidence rates, and annotated step-by-step solutions to numerical problems. In addition, the text introduces topics sometimes ignored in other texts, such as hybrid studies, the controversy surrounding the use of hypothesis testing versus confidence intervals, and the differences between rate and risk measurements. Study reference for NEHA's REHS/RS exam.
368 pages, paperback.
