I am a graduate student in Psychology, and I find the Hays text mostly illegible. His prose is dense and his explanations rely very heavily on mathematical formulae instead of real-world or logical/verbal descriptions. Furthermore, he falls into the typical "math textbook" pit of giving solutions to only the example problems that are exceptions to what one would usually encounter.
This is especially bad considering that my concentration specializes in statistical inference, and I've studied mathematics through differential equations (including linear algebra, multivariate).
Worse, Hays has a tendency to use different symbols to represent variables compared to other statistical texts (and in some cases, the rest of the world!)
Lastly, the tables that Hays has in the back of his book are not notated. He does not explain what each table represents, or what the x or y axis are. In one case, he has two entries for each lookup in the ANOVA Power of Association (omega squared) (Table XII, page 1032). Nowhere in the table does it mention what these two values are for.
It is only in one paragraph 600 pages earlier, that he explains that the two values are for alpha=0.05 and 0.01 and that n must be equal for both groups!! (page 410)
I am currently relying on several other texts to understand statistics for the social/behaviourial sciences. If you are extremely comfortable with mathematics to describe your behaviourial tests, you may find this book valuable. If you prefer a more descriptive approach, I suggest another one.
This text is for the mathematically inclined-it is not a "how-to" book, rather a "why" book that thoroughly explains the theory behind a variety of popular inferential techniques. If this is the sort of knowledge you are seeking, Hays is the book for you. If you are interested in a more "common-sense" or applied approach, perhaps you should look elsewhere.

Provides an in depth look at statistics. I had to buy this book in my PhD program and lost it. This is a replacement.Published 14 months ago by M. Rutherford
What can I say. This is a classic. You can not go wrong with Hays. If you are getting a faculty position, buy one and keep it on your shelf. It will buy you some respect.Published 24 months ago by W
