Reliability, from the Understanding Statistics series of books that aims to provide researchers with authoritative guidance for understanding, presenting, and critiquing statistical analysis, shows how to report relevant topics—including details about what to say, how to say it, and drawing the line between What cannot be properly claimed or concluded about its authenticity. This book focuses specifically on "reliability," a fundamental aspect of social science research. "Reliability" affects not only the quality of test scores but also any statistical analysis based on those scores. The topics presented in this book include three different reliability methods and accepted standard errors: including traditional test theory methods, decision stability indicators, and generalizability theory. After a brief introduction to each topic, the book explains how "reliability" should be reported in professional journal articles.
