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. 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. This approach motivates the student by demonstrating how the procedure works and how it contributes to the decision-making process.
