I bought the Design and Analysis of Experiments book, 7th edition, softcover, with the erlenmeyer filled with corn cover. It's the same quality of the hardcover, and cheaper, which is better for those who doesn't care about hardcover. I hate those indian low cost editions. this one is way better, because the pages are made with that glossy paper which isn't thick but not transparent, making the book thinner and lighter than others.
This book loves to make everything so much more complicated. I've taken Statistics three years ago, and this book is just a big mess. Also, the international edition doesn't have the same questions as the US edition.
I needed this book for a class and it was expensive everywhere else I looked. So I decided to take the plunge and just get a cheaper one from Ebay. It was cheap, yes but it came to me on time and in excellent conditions. I'll totally recommend buying books from here.
I have used Montgomery books earlier for my Stat. courses. This book was recommended by the professor. It explains matter clearly with several examples. An answer key to the exercises would have been a great help.
The book is not hardcover as mentioned and the book also printed on the thin paper. I can see through next page. This is the first book and also the last book I bought.
