This is the new edition of the book we used in the marketing research course at the Michigan Business School. It was great then and is even better now that they have tightened it up and slimmed it down a bit. It reads clearly, is focused, and doesn't pull any punches about the benefits, tradeoffs, and limitations of the various problems and methods involved in this subject.
Rather than focusing on decision support systems or marketing information systems, this book is focused on a project based approach. The authors help you recognize a problem, how to formulate it clearly, present it to decision makers for approval, designing the research to be done, data design and collection methods, they offer sample designs which is very helpful. They then do a fabulous job on data analysis and conclude by showing you how to present a proper research report.
There are several helpful appendices providing statistical values for those calculator based problems, but, really, who doesn't use a spreadsheet or SPSS or some similar package anymore?
There is also a glossary, a subject index, and an author index.
This is a standard text on the subject, and it is terrific.
