If you use statistics and need a useful, up-to-date and reliable sourcebook that provides simple definitions and explanations of statistical concepts, especially those used in biomedicine, then you will need this dictionary. Over 2000 terms are included here; Professor Everitt has aimed to provide brief but useful descriptions of those terms frequently found in the medical and medical statistics literature. Where appropriate, graphical illustrations or numerical examples are given, and the use of mathematical formulae has been minimised. This will be an essential reference for workers in all branches of medicine, applied statistics and biostatistics, especially research workers and research oriented clinicians.
