Regression toward the mean is a complex statistical principle that plays a crucial role in any research involving the measurement of change. This primer is designed to help researchers more fully understand this phenomenon and avoid common errors in interpretation. The book presents new methods of graphing regression toward the mean, facilitating comprehension with a wealth of figures and diagrams. Special attention is given to applications related to program or treatment evaluation. Numerous concrete examples illustrate the ways researchers all too often attribute effects to an intervention or other causal variable without considering regression artifacts as an alternative explanation for change. Also discussed are instances when problems are actually created, instead of solved, by "correction" for regression toward the mean. Throughout, the authors strive to use nontechnical language and to keep simulations and formulas as accessible as possible.

"Comprising more than 500 entries, the Encyclopedia of Research Design explains how to make decisions about research design, undertake research projects in an ethical manner, interpret and draw valid inferences from data, and evaluate experiment design strategies and results. Two additional features carry this encyclopedia far above other works in the field: bibliographic entries devoted to significant articles in the history of research design and reviews of contemporary tools, such as software and statistical procedures, used to analyze results. It covers the spectrum of research design strategies, from material presented in introductory classes to topics necessary in graduate research; it addresses cross- and multidisciplinary research needs, with many examples drawn from the social and behavioral sciences, neurosciences, and biomedical and life sciences; it provides summaries of advantages and disadvantages of often-used strategies; and it uses hundreds of sample tables, figures, and equations based on real-life cases."--Publisher's description.

Für Studium und Weiterbildung werden institutionelle Rahmenbedingungen, wissenschaftstheoretische Grundlagen, methodische Gütekriterien und praktische Verfahren für empirische Untersuchungen psychologischer, evaluativer und verwandter Probleme dargestellt. Im Mittelpunkt steht die Validität und damit die Güte und Qualität von Untersuchungen wissenschaftlicher und praktischer Fragestellungen. Diese umfasst vor allem die Adäquatheit von Begriffen, deduktiven und induktiven Argumenten, kausalen Aussagen, Gesetzeshypothesen und Theorien, die Kontrolle störender Einflüsse bei Beobachtungen, Befragungen, Einschätzungen (ratings), Messungen, Tests, Experimenten, Quasi-Experimenten, Fall-Kontroll- und Einzelgruppenstudien sowie die sachgerechte Anwendung und Interpretation von statistischen Zusammenhängen und Tests, Varianz-, Regressions- und Meta-Analysen, festen, zufälligen und hierarchisierten Faktoren. Ziel ist ein tiefergehendes Verständnis wesentlicher Qualitätsmerkmale empirischer Untersuchungen, um fundiert Methoden einsetzen und Ergebnisse interpretieren zu können.
