    The reviewers have been asked to rate these books in terms of four items: readability, how up to date they are, accuracy and reliability, and value for money, using simple four point scales. From their opinions we have derived an overall "star" rating: * = poor, ** = reasonable, *** = good, **** = excellent.

    This book describes the essentials of statistics and data presentation. The first chapters deal with the different types of study designs, the various forms of data and the characteristics of pictorial forms of presenting data. Subsequent chapters deal with distributions, means and medians, and measures of variability. The author describes confidence intervals, p values, statistical power, and type I and II errors. The final sections are on confounders, interactions, measures of correlation, hierarchy of evidence, causality, and how to assess papers. The author describes the terms used in evidence based medicine such as absolute risks and the number needed to treat. A glossary of terms used is contained in the appendices.

    The book will be of invaluable use for those just starting a research career or in its early stages. It is comprehensive and clearly written with many illustrative examples. The text covers well all the areas that are of interest to those commencing their own research projects. The pitfalls of different tests are well described and the book is competitively priced.
