The sixth edition ofBusiness Statistics for Contemporary Decision Makingcontinues the rich
tradition of using clear and complete, student-friendly pedagogy to present and explain
business statistics topics. With the sixth edition, the author and Wiley continue to expand
the vast ancillary resources available through WileyPLUS with which to complement the text
in helping instructors effectively deliver this subject matter and assisting students in their
learning. The resources available to both the instructor and the student through WileyPLUS
have greatly expanded since the fifth edition was launched; and because of this, an effort has
been made in the sixth edition to more fully integrate the text with WileyPLUS.
In the spirit of continuous quality improvement, several changes have been made in
the text to help students construct their knowledge of the big picture of statistics, provide
assistance as needed, and afford more opportunities to practice statistical skills. In the
fifth edition,the 19 chapters were organized into four units to facilitate student understanding of the bigger view of statistics. In the sixth edition, these same 19 chapters have
been organized into five units so that chapters could be grouped into smaller clusters. The
nonparametric and the analysis of categorical data chapters have been moved further
toward the back of the text so that the regression chapters can be presented earlier. The
decision trees that were introduced in the fifth edition to provide the student with a taxonomy of inferential techniques have been improved and expanded in the sixth edition.
Nonparametric inferential techniques have been separated from other inferential techniques
and given their own decision tree. This has simplified the decision trees for parametric techniques and made the decision trees easier for students to decipher. Further integration of the
text with WileyPLUS is addressed through icons that are used throughout the text to designate to the reader that a WileyPLUS feature is available for assistance on a particular
topic. The number of databases associated with the text has been expanded from seven to
nine, and one of the fifth edition databases has been replaced, thereby bringing the total of
new databases in the sixth edition to three.
All of the features of the fifth edition have been retained, updated, and changed as
needed to reflect today’s business world in the sixth edition. One Decision Dilemma has
been replaced, and nine new Statistics in Business Today features have been added. In the
sixth edition, as with the fifth edition, there are 17 high-quality video tutorials with the
author explaining key difficult topics and demonstrating how to work problems from challenging sections of the text.
