I've been using Discovering... with SPSS... for a couple of years & have just updated to the 5th edition. I LOVE chapter 3, and have actually been covering a lot of that material in my class, so it's nice to have it explicit in the text as well.

"By the way, has anyone had a chance to look at the text? I love it! It's the first text I've come across that has been written in such a captivating way. There's humor, tons of information, and awesome resources both within and on the companion website. Kudos to Prof. Field!"

Anonymous Student, Harvard University

"I never thought I would find a statistics textbook amusing but somehow our text pulls it off.  I also appreciated the online supplementary tools provided by the publisher.  If you haven't seen them yet, you should check them out.  They provide a good synthesis of each of the chapters and some easy options to review."

Anonymous Student, Harvard University

"I get started on the text and can't agree more with you on how the book is. I also appreciate how the author made the text interesting to read, but the content is rich enough to provide readers good knowledge on how to draw insights from stats and data. Also, it provides a lot of practical guides for reporting results and findings for research paper. Can't wait to take a deeper dive into the text!"

Excellent, well organized text. Unique, in my experience, the text and substantial student support website, provide supplemental materials for students who may be struggling and advanced materials for those who are ready. This facilitates course design and teaching in classes where a mix of preparation backgrounds is the norm.

I've had previous editions of this text and as always, I am very impressed with Dr. Fields' humorous approach to statistics. He provides instruction on conducting analyses in the most current version of SPSS and has included Bayesian statistics in the new edition. Students receive comprehensive statistical instruction and many online resources are also provided. This is the best statistics textbook!
