Product Description Essential Biostatistics teaches students how to interpret statistical results by explaining the ideas behind statistics in nonmathematical terms. Rather than replacing longer, more traditional mathematical textbooks, this text is designed to supplement them. With its engaging and conversational tone, this unique book provides a clear introduction to statistics for students in a wide range of fields, and also serves as a statistics refresher for working scientists. It is especially useful for those students in health-science related fields who have no background in biostatistics. KEY FEATURES Explains the ideas of statistics without describing the mathematical underpinnings Designed for the many students and scientists who prefer verbal explanations over mathematical proofs Focuses on how to avoid falling into common conceptual traps Works to point out ambiguities in potentially confusing terms and phrases Covers a wide breadth of topics in a quick and concise manner Review "Motulsky seems to have done the impossible, again. He has taken his already great textbook and extracted the bare-bones necessary for the reader to enjoy a lively, easy-to-read introduction to the concepts of biostatistics. In addition, Motulsky provides the reader with a discussion of common mistakes and how to avoid them. Essential Biostatistics should be required reading for all beginning biology or biostatistics students. It provides foundational material for interpreting statistical analysis." --Philip Hejduk, University of Texas at Arlington "The author does a great job explaining WHY we use statistics rather than getting bogged down explaining HOW we calculate statistics. I find it refreshing to step back from the calculations to see the larger context why we use statistics in science." --Dean W. Coble, Stephen F. Austin State University "I really like the clear and humorous style, the wealth of examples, and the discussions of the limits and pitfalls.
