Preface Statistics is seldom the most eagerly anticipated course of a business student. It generally has the reputation of being a humdrum, complicated, and confusing mix of mathematical formulas and computers. Our goal in writing this casebook and the companion volume (Business Analysis The use of Regression) used to be to change that impression by showing how statistics yields insights and answers interesting business questions. Slightly than dwell on underlying formulas, we show how to use statistics to reply to questions. Each case study begins with a business question and concludes with an answer to that question. Formulas appear only as needed to address the questions, and we focus on the insights into the problem provided by the mathematics. The mathematics serves a purpose. The material in this casebook is organized into 11 “classes” of related case studies that develop a single, key idea of statistics. The analysis of data The use of statistics is seldom very straightforward, and each analysis has many nuances. A part of the appeal of statistics is this richness, this blending of substantive theories and mathematics. For newcomers, on the other hand, this blend is too rich, and they are easily overwhelmed and unable to sort out the important ideas from nuances. Even supposing later cases in these notes suggest this complexity, we don’t begin that way.
