简介：New edition of a text in which Robert S. Witte (San Jose U.) and John S. Witte (Case Western Reserve U.) present a simple overview of descriptive and inferential statistics. Written with the intent to help students gain the confidence needed to use statistics in their everyday lives, the 26 chapters cover introductory material (definition of statistics, and two types of data and variables), organizing and summarizing data, and generalizing beyond data. Each chapter contains outlines, summaries, key terms, marginal definitions, and real-life exercises. Annotation c. Book News, Inc., Portland, OR (booknews.com)
