“Kirk is an extraordinarily logical and precise writer. His prose is excellent. I really like the balance between the logic and issues of design and the assumptions and implications of violations in the analysis. The consistent explanation of the parameters of the model equation and the sample estimators of the parameters is so clear. The advantages and disadvantages sections are wonderful and the diagrams comparing partitioning of variances are elegant.”

Jim Dykes, The University of Texas at San Antonio

“This is the standard for texts in experimental design. It is truly an outstanding resource. The expansive coverage of the full range of designs and all their complexities make it extremely valuable. The extensive updating throughout this edition will be a great asset for instructors. The general conceptual approach taken in the building block approach to designs is very helpful to graduate students studying the concepts for the first or second time. I have always thought the examples in this book are clear and well developed, truly ideal. I appreciate the many new exercises for students in this new edition, as well.”

Dale R. Fuqua, Oklahoma State University

“The book is thorough in integrating important topical areas dealing with statistical power and effect size estimation within the chapters covering a particular design and analysis issue.”

William P. Neace, University of Hartford

“This is still the best available textbook on experimental research.”

Lihshing Leigh Wang, University of Cincinnati

“The combination of topic coverage and organization, depth of coverage, and clarity of writing are what keeps me using this text year after year."

James L. Wardrop, University of Illinois at Urbana-Champaign

“I like the examples given to solidify important points, and how in some spots the author clearly spells out concepts for the reader. I like how it would be easy to quickly grab this text and look up issues of determining effect size and acceptable levels without doing much digging, and how the advantages and disadvantages of certain designs are clearly identified. I also like that he includes references from the updated APA manual. It is nice to see that kind of consistency.”

Jessica M. Nicklin, University of Hartford

“Professor Kirk continues, with this Fourth Edition, to maintain his high standards of clarity and scholarship. Many important designs and analyses for behavioral researchers are succinctly and lucidly presented. It is written at such a level as to be beneficial for the graduate student and yet does not sacrifice conceptual/technical issues (esp. by explicating and utilizing the GLM approach). This makes this edition not only a very good textbook but also an exceptional reference book.”

Charles A. Dill, Hofstra Universiy

“Kirk has very useful chapters for addressing complicated designs. Addressing confounded and fractional designs can seem a bit arcane to students, but knowing how to use them can help researchers to either avoid them or recognize situations in which they are used.”

Amy Lynne Shelton, The Johns Hopkins University

“The materials are logically and well organized. The layout of these materials is from lower level to higher level; and from basic conceptual interpretation to complicated computational procedures and experimental designs.”

Dabae Lee, Indiana University

“I would really like to see students think of this book the way I do—like an old friend that I would NEVER be without.”

Valerie L. Shalin, Wright State University
