| I am a graduate student at ASU. This book is part of the required course materials, since Montgomery is affiliated with ASU. The quality of this textbook is what you may find in a mediocre $40 statistics book. I have not seen statistics dealt with in a more confusing manner. Explanations are incomplete, graphs meant to illustrate concepts are not labeled, symbols and functions are used without defining them, and there are errors in the examples. My understanding was that D. Montgomery has been in this field for a long time. However, basic principles, like including units with the data, are ignored. I expected by the 6th attempt these problems would have been worked out. The other reviews do not make sense to me, since my classmates feel a similar frustration with the book. |
