This long awaited successor of the original Cook/Campbell Quasi-Experimentation: Design and Analysis Issues for Field Settings represents updates in the field over the last two decades. The book covers four major topics in field experimentation: - Theoretical matters: Experimentation, causation, and validity;
- Quasi-experimental design: Regression discontinuity designs, interrupted time series designs, quasi-experimental designs that use both pretests and control groups, and other designs.
- Randomized experiments: Logic and design issues, and practical problems involving ethics, recruitment, assignment, treatment implementation, and attrition.
- Generalized causal inference: A grounded theory of generalized causal inference, along with methods for implementing that theory in single and multiple studies.
- The final chapter critically reflects on the assumptions and key issues covered in the previous four sections.
The emphasis on the generalized causal inferences is a significant extension of the work done in previous volumes; and the addition of theoretical and practical chapters on randomized experiments will be of great use to researchers who use randomization in their research practice. At the same time, this book retains and expands the emphasis on quasi-experimentation that was the hallmark of Cook and Campbell; and it retains Campbell's classic theoretical and conceptual approach to experimentation that has been so successful over the last 35 years.

Experimental and Quasi Experimental Designs
»
The book arrived in good shape and withing promised time. However when I order books from other sellers they are shipped rightaway and if they have not been shipped it is easy to cancel the order. With Amazon when I tried to cancel the order it said that the order has been processed but it was shipped a week after that. I guess that is the price one has to pay for free shipping.

Great book
»
This is a great book for those who are willing to discover or improve their knowledge about experimental and quasi-experimental designs - it is an essential book, I'd say. It also helps a lot to understand research and science in general. Really helped me in my dissertation.

Excellent for doctoral students
»
I am a doctoral student in public health and recommend this book to my fellow doctoral students out there. It is a thorough and comprehensive text on research methods. I have gone through quite a few texts with similar titles and this stands out as the best.

Very frustrating
»
I am a first year Ph.D. student, and I find this book quite frustrating to read. The reading drags on and on, and I can't really remember what I read. The examples in the book are somewhat helpful, but they do not seem to fully explain the concepts very well. I hope the next edition will have a more comprehensive explanations for the concepts in the book.

Very informative.......
»
but very boring too! Actually, that's not completely true, it's just the first few chapters that are excruciatingly boring, but once you get past all the introductory material, it's quite informative. I'm reading this right now for my graduate course in experimental design, so I most likely found the first few chapters as boring as I did because I already knew the stuff. Although some pictures would be nice, and I'm talking about more than just the illustrations that they use to...uh... "illustrate" different experimental designs, it's nice that there's not a bunch of fluff to sort through looking for the information that is actually important. It's a well written and pretty easy to comprehend must have for those of in the wacky world of experimental studies.
