The case studies are interesting and has a wealth of data sets. However for teaching the examples are poorly written, often convoluted and largely useless for learning. Often the text is along the lines of assume X = xxxx, Y = xxxx, thus the answer is . With little to no explanation short of the generic formula/law/axiom. As well as one, at best two, said examples.Another flaw is the horrible lack of solutions to problems contained in the book. Only about a third of the end of chapter problems have a solution in the book/cd, and it is just the solution with zero info on how it is obtained.
