Book Description

Essentials of Business Statistics: Communicating with Numbers; 2nd Edition; (PDF) is a core statistics textbook that ignites student interest and breaches the gap between how statistics is taught and how practitioners think about and apply statistical methods. Throughout the textbook; the focus is on communicating with numbers rather than on number crunching. By including the perspective of professional users the subject matter is more relevant and the presentation of material more straightforward for students. Connect is the only integrated learning system that enables college students by continuously adapting to provide precisely what they need when they need it and how they need it so that your class time is more effective and engaging.
