Evidence-based medicine aims to apply the best available evidence gained from the scientific method to medical decision making. It is a practice that uses statistical analysis of scientific methods and outcomes to drive further experimentation and diagnosis. The profusion of evidence-based medicine in medical practice and clinical research has produced a need for life scientists and clinical researchers to assimilate biostatistics into their work to meet efficacy and practical standards. Practical Biostatistics provides researchers, medical professionals, and students with a friendly, practical guide to biostatistics. With a detailed outline of implementation steps complemented by a review of important topics, this book can be used as a quick reference or a hands-on guide to effectively incorporate biostatistics in clinical trials.

Key Features

  • Customized presentation for biological investigators with examples taken from current clinical trials in multiple disciplines
  • Clear and concise definitions and examples provide a pragmatic guide to bring clarity to the applications of statistics in improving human health
  • Addresses the challenge of assimilation of mathematical concepts to better interpret literature, to build stronger studies, to present research effectively, and to improve communication with supporting biostatisticians


Investigators and clinicians involved in genetics, genomics, immunology, virology, microbiology, cell biology, pharmacology, and biomedical research; post-doctoral fellows and graduate researchers; physicians who need to make evidence-based clinical decisions; physicians and medical students who consult medical literature which demands knowledge on biostatistics; instructors and trainees in national and international technical clinician and degree programs
