Not as Good as the 6th Edition!, November 20, 2005
I am currently teaching statistics (using a different textbook) and have been using the 6th edition of Hogg/Tanis as a reference. In my opinion, this is a pretty good text for someone who A) already has some idea of what statistics is all about and B) has a thorough understanding of calculus, which Hogg/Tanis make liberal use of. For someone who likes and understands calculus,
this is a much better introductory text than those that studiously avoid any mention of higher level mathematics. I give the 6th edition a 5-star rating based on the sections I've looked at so far.
With that said, I'm sorry to report that the 7th edition is not as good as the 6th. The authors have re-organized the material "for better logical organization", but in the process have lost some pedagogical clarity. For example, the relatively important student's t distribution has been relegated to an obscure example buried in a new chapter on the normal distribution, and the formerly excellent explanation of how this is derived is gone.
And speaking of "The Normal Distribution" chapter, do I really want all things normal relegated to a separate chapter? The pervasive use and importance of this distribution in statistics makes me think that it might be better to let the normal distribution pop up whenever it needs to be invoked, as was the case in the 6th edition. Including a "Sampling Distribution Theory" chapter (as was done in the 6th edition) makes a lot more sense than what they've done now. The new chapter on Bayesian Methods is short, and not terribly useful. Relegating this material to section 9.5 in a chapter on "Theory of Statistical Inference", as was done in the 6th edition was a much better decision.
The section on "Exploratory Data Analysis" (histograms and stemplots) has been moved from an introductory chapter (which no longer exists) to the chapter on "Continuous-Type Data". How does this make any sense? And yes, it is most definately a good idea to have an introductory chapter which talks about basic concepts and data visualizations. In the 7th edition, the mean, median, and standard deviation are first mentioned in chapter 2.
Finally, why on earth do authors think that randomly adding color to a textbook and widening the pages to allow for giant margins on every page makes a text more readable/useful when in fact just the opposite is the case? The wide margins add nothing and make the book both heavier and more unwieldy, and the blue section headings and graphs give it the feel of a junior high school algebra text. The compact elegance of the 6th edition stands in stark contrast to the large and comparatively garish 7th edition.
This revision has all the feel of something that was driven strictly by textbook marketing concerns and has nothing to do with either pedagogy or an interest in producing a excellent statistics book.
My advice? If you're looking for something for self-study or reference, get the 6th edition instead. It's better, and you can get a used copy on Amazon for next to nothing, since the lemmings have all switched to using the 7th edition and there are a lot of unwanted copies of the 6th floating around.
The nonsense of constantly producing new (and often inferior) editions of textbooks just so that publishers can make more money needs to be nipped in the bud.

Don't buy this book!, December 12, 2000
This review is from: Probability and Statistical Inference (6th Edition) (Hardcover)
There are good books on probability and statistical inference. This isn't one of them! If you are hunting for something - look for authors like James T. McClave or P. George Benson. James McClave has written some good books in this area.
Examples are HARD TO FOLLOW. There is no development of concepts. The writer doesn't seem to have any idea how to explain or how to provide examples. THIS IS NOT A BOOK THAT NORMAL PEOPLE CAN UNDERSTAND! IF YOU LIKE MATH OR WOULD LIKE TO UNDERSTAND MATH - DON'T BUY THIS BOOK! It does provide an example of what a book shouldn't look like!

2.0 out of 5 stars
thorough but very confusing and badly written, July 17, 2003
By A Customer
This review is from: Probability and Statistical Inference (6th Edition) (Hardcover)
I taught prob/stat from 99-02. The first year we used Tanis and Hogg 5th, the second 6th Edition, and the last two semesters were the current Larsen and Marx (much nicer IMO, at least on the readability and organization factor). I felt the 6th was a step backwards from the 5th in terms of organization and the 5th wasn't great for that. In fact, the 6th felt a lot more like the old 3rd edition I had when I was taking prob/stat for the very first time. In my experience, many of the flaws that other reviewers have noted are present in this book:
-Confusing transitions between theorems and examples in the main text, with theorems and examples not clearly delineated from surrounding text (particularly where they end), making it hard to use the book for reference as you work problems;
-Examples that have too many steps skipped;
-Problems which are often much more difficult than the examples in the text (that said, many of the problems in T&H are quite good, which I suspect explains the longevity of it as a text, well that, simple inertia among profs who have their lectures already written, and the publisher's sales staff :).
*I* could use it as a reference as it does cover a lot of topics pretty well. So what. If I'm teaching the material I *better* have a mastery over the material in the book! Student have got to be able to use it and they don't have that mastery. Bad organization simply obscures the material which, while not difficult from a straight mathematical standpoint, IS pretty difficulty conceptually IME.
