This groundbreaking work by leading social psychologists, who have all contributed in important ways to the psychology of group perception, focuses in particular on three interrelated issues: (1) whether groups are seen to be diverse or relatively homogeneous; (2) whether groups are seen as real and stable or only transitory and ephemeral; and (3) whether group membership derives from some essential quality of the members or rather is based on social constructions.

This indispensable collection provides extensive, yet accessible, coverage of conceptual and practical issues in research design in personality and social psychology. Using numerous examples and clear guidelines, especially for conducting complex statistical analysis, leading experts address specific methods and areas of research to capture a definitive overview of contemporary practice. Updated and expanded, this third edition engages with the most important methodological innovations over the past decade, offering a timely perspective on research practice in the field. To reflect such rapid advances, this volume includes commentary on particularly timely areas of development such as social neuroscience, mobile sensing methods, and innovative statistical applications. Seasoned and early-career researchers alike will find a range of tools, methods, and practices that will help improve their research and develop new conceptual and methodological possibilities. Supplementary online materials are available on Cambridge Core.

This essential textbook provides an integrated treatment of data analysis for the social and behavioral sciences. It covers all the key statistical models in an integrated manner that relies on the comparison of models of data estimated under the rubric of the general linear model.The text describes the foundational logic of the unified model comparison framework. It then shows how this framework can be applied to increasingly complex models including multiple continuous and categorical predictors, as well as product predictors (i.e., interactions and nonlinear effects). The text also describes analyses of data that violate assumptions of independence, homogeneity, and normality. The analysis of nonindependent data is treated in some detail, covering standard repeated measures analysis of variance and providing an integrated introduction to multilevel or hierarchical linear models and logistic regression.Highlights of the fourth edition include:Expanded coverage of generalized linear models and logistic regression in particularA discussion of power and ethical statistical practice as it relates to the replication crisisAn expanded collection of online resources such as PowerPoint slides and test bank for instructors, additional exercises and problem sets with answers, new data sets, practice questions, and R codeClear and accessible, this text is intended for advanced undergraduate and graduate level courses in data analysis.Access the Instructor Resources for this title at routledgetextbooks.com/textbooks/instructor_downloads

Data Analysis: A Model Comparison Approach to Regression, ANOVA, and Beyond is an integrated treatment of data analysis for the social and behavioral sciences. It covers all of the statistical models normally used in such analyses, such as multiple regression and analysis of variance, but it does so in an integrated manner that relies on the comparison of models of data estimated under the rubric of the general linear model. Data Analysis also describes how the model comparison approach and uniform framework can be applied to models that include product predictors (i.e., interactions and nonlinear effects) and to observations that are nonindependent. Indeed, the analysis of nonindependent observations is treated in some detail, including models of nonindependent data with continuously varying predictors as well as standard repeated measures analysis of variance. This approach also provides an integrated introduction to multilevel or hierarchical linear models and logistic regression. Finally, Data Analysis provides guidance for the treatment of outliers and other problematic aspects of data analysis. It is intended for advanced undergraduate and graduate level courses in data analysis and offers an integrated approach that is very accessible and easy to teach. Highlights of the third edition include: a new chapter on logistic regression; expanded treatment of mixed models for data with multiple random factors; updated examples; an enhanced website with PowerPoint presentations and other tools that demonstrate the concepts in the book; exercises for each chapter that highlight research findings from the literature; data sets, R code, and SAS output for all analyses; additional examples and problem sets; and test questions.
