Book News Annotation:
This textbook provides an introduction to business statistics using data from real companies to illustrate various concepts. A sampling of topics includes sampling methods, continuous probability distributions, nonparametric methods, decision theory, and total quality management. The fourth edition also features a new chapter on model building. The volume makes extensive use of Data Analysis Plus 3.0 (included on the CD-ROM) to carry out the statistical tests and procedures covered in the text.

'Highly praised for its clarity and great examples, Weiers\' text takes an informal, student-oriented approach to presenting fundamental statistical concepts. Non-technical terminology and outstanding illustrations explain statistical concepts presented in the context of contemporary applications and student experience. Aware that many business students are intimidated by this course, Weiers provides numerous learning aids and interesting applications drawn from real-world experience common to many students.'
