Business statistics made accessible

Donnelly’s conversational writing style, friendly step-by-step approach, clearly presented concepts, and skillful use of business-focused examples give meaning to business statistics for today’s college students. From the moment they open the book, students get the sense of sitting down and having a conversation with the author.

• The engaging, straightforward tone pulls students into the material, without talking down to them, and helps them understand the concepts even before they realize they’re learning.
• The look and feel of the book is designed to be friendly and unintimidating.
• Key concepts — and why students need to know them — are effectively explained.
• Author comments in the margins call out quick tips and common mistakes to help clarify specific topics. Presented informally as written bubbles, they’re analogous to side comments instructors would make to students during a lecture to help them understand the material.
