Effect Sizes for Research: Univariate and Multivariate Applications, Second Edition
"This book presents an excellent summary of the debate around the use of null hypothesis significance testing and includes a lot of examples and practical advice to researchers about the software and methods needed to report effect size. Coverage of different models is wide and much of the material will be highly relevant to psychologists working in many fields."-Chris Beeley, Senior Evaluation Manager, Institute of Mental Health, Nottingham, UK, inThe Psychologist"This book is the single-best, definitive treatment of effect sizes, and is best characterized by the following adjectives: comprehensive, contemporary, clear, concrete, accessible, practical, and well-organized."-Bruce Thompson, Texas A&M University and Baylor College of Medicine, USA"This is THE essential guide to effect sizes and confidence intervals: authoritative yet accessible, detailed yet entirely practical. It needs to be close to the elbow of every serious researcher and graduate student."-Geoff Cumming, La Trobe University, Melbourne, Australia"Effect sizes and associated confidence intervals are increasingly recognized as a more informative basis for inferences than p-values. This helpful book introduces a wide array of tools to enable researchers to fulfill this agenda."-Robert G. Newcombe, Cardiff University, UK"This book provides accessible, comprehensive coverage of effect sizes and their interpretation. I have used the first edition as a required text for a course on interpretation of data and plan to continue to use it. Researchers, both novice and experienced, will also find the book to be a valuable reference."-Patricia A. Shewokis, Drexel University, USA"A thousand copies of this book should be dropped from a low flying airplane over ... the 4,200 college and univeristy campuses in America. ...

This book should be required reading for all graduate faculty, students, and workers in the field."-Shlomo Sawilowsky, Wayne State University, USA"It is important for graduate students to understand effect size in multivariate statistics. ... The book presents a good theoretical background on the effect sizes for various statistical procedures and it is ... way ahead of other books. ... The authors write well.... It [is] an excellent text on effect sizes. ... I would ... use the book in my course."-Aman Yadav, Purdue University, USA
