Introduction to modern statistecs: with applications to business and economics

The necessity for equipping students of business and economics with a basic knowledge of statistical methods is widely recognized. However, there is considerable divergence as to character and purpose among the courses offered to fulfill this need.
In many institutions, it is impractical to assume that students enter the introductory course in statistics with sufficient knowledge of mathematics to master statistical theory.
This is the point of view from which this book has been written. Con cepts are introduced by concrete examples rather than in the abstract. The reasoning underlying a given method for solving a problem is then presented in relation to the example. Mathematical rigor has been sacrificed to some degree to ease the assimilation of major ideas, and the exposition is occa sionally interrupted by bits of material in a lighter vein, in the hope that students will find that statistics is neither too difficult nor too tedious.
The book is arranged primarily to meet the needs of schools of business and departments of economics that offer a three- or four-unit introductory statistics course. In order to provide flexibility, slightly more material is included than will commonly be covered in such a course.
