内容简介：
This book describes the most commonly used statistical methods. It is written at an introductory level. No calculus is used, but some familiarity with algebra is necessary. It could be used in an introductory course in statistics or biostatistics. One feature of the book is that much guidance is given concerning the selection of statistical methods. In addition, the chapter on categorical data includes many statistical methods that are not found in most introductory texts.
