Summary: This readable revision is presented as simply as possible to ensure that readers will gain a solid understanding of statistical procedures. The goal of this book is to demystify statistics. Presented with rules of evidence and the logic behind those rules. The book is divided into three major units: Descriptive Statistics, Inferential Statistics, and Advanced Topics in Inferential Statistics. Includes definitions of key concepts in the glossary to prevent confusi ...show moreon over terminology. Presents a brief biography of six people who have had the most impact on the field of statistics. Offers new and easier methods for finding percentiles in Chapter 5. For anyone interested in Social Statistics and Measurement. ...show lessEdition/Copyright: 6TH 00
