If you use statistics and need a useful, up-to-date and reliable sourcebook that provides simple definitions and explanations of statistical concepts, then you will need this dictionary. Some 3000 terms are defined in all areas of statistics, including medical, survey, theoretical, applied etc. In addition short biographies are given of over 100 important statisticians. The majority of definitions include a reference to a book or article where the reader can seek an extended account of a term if required. Many of the definitions are accompanied by graphical material to aid understanding. The book is a 50% expansion of Everitta€™s successful earlier title, aimed specifically at medical statisticians.
