This revision of the classic Quantitative Methods for Business is designed to provide students with a conceptual understanding of the role that quantitative methods play in the decision-making process. The text describes the many quantitative methods that have been developed over the years, explains how they work, and shows how the decision maker can apply and interpret data. The book has been written with the non-mathematician in mind; it is applications-oriented. In each chapter a problem is described in conjunction with the quantitative procedure being introduced. The authors have found that this approach helps to motivate the student by demonstrating not only how the procedure works, but also how it can contribute to the decision-making process.
