### Description

It is not necessary to know how to do a statistical analysis to critically appraise a paper. However, it is necessary to have a grasp of the basics, of whether the right test has been used and how to interpret the resulting figures. Short, readable, and useful, this book provides the essential, basic information without becoming bogged down in the mathematical detail that often puts so many readers off statistics. It covers all the ground necessary to critically evaluate the statistical elements of medical research papers in an approachable way. This book is designed for healthcare students and professionals who need a basic definition and knowledge of common statistical terms.
