Summary:

Basic Biostatistics: Statistics for Public Health Practice, Second Edition is a concise, introductory text that covers biostatistical principles and focuses on the common types of data encountered in the public health and biomedical fields. Sampling, exploratory data analysis, estimation, hypothesis testing, and power and precision are covered through detailed, illustrative examples. Organized into three parts, the book examines basic concepts and techniques; analytic techniques for quantitative response variables; and techniques for categorical responses. The Second Edition offers many new exercises and expanded resources for instructors. With language, examples, and exercises that are accessible to students with modest mathematical backgrounds, this is the perfect introductory biostatistics text for undergraduates and graduates in various fields of public health. Features: Illustrative, relevant examples and exercises incorporated throughout the book. Equal attention is given to manual calculations as well as the use of statistical software such as StaTable, SPSS, and WinPepi.
