Description Today, mathematics, biology, medicine, and statistics are closing the interdisciplinary gap in an unprecedented way and many of the important
unanswered questions now emerge at the interface of these disciplines. Now in its Second Edition, this user-friendly guide on biostatistics
focuses on the proper use and interpretation of statistical methods. This textbook does not require extensive background in mathematics,
making it user-friendly for all students in the public health sciences field. Instead of highlighting derivations of formulas, the authors
provide rationales for the formulas, allowing students to grasp a better understanding of the link between biology and statistics. The
material on life tables and survival analysis allows students to better understand the recent literature in the health field, particularly
in the study of chronic disease treatment. Biostatistics now includes a companion website to demonstrate the different applications
of computer packages for performing the various analyses presented in this text.
Audience
Students in the health sciences, public health professionals, practitioners.
