Any textbook writer knows how exciting it is to create a new edition. Since the sixth version of this book was published five years ago, I've listened to students and teachers who are using it and have gained the following advice from them. The book's title must reflect the fact that the majority of the examples and exercises deal with significant management issues. The prudent researcher understands the need for a deeper understanding of the data, so there must be a separate chapter on an application-oriented introduction to multivariate analysis. Since the findings of a research project must always be shared with others, there must be a chapter on Report and letter-writing and Oral Preparation.
