Relevant statistical methods that empower individuals to make effective, data-informed business decisions
Business Statistics, 4th Edition, by Sharpe, Sharpe, De Veaux, and Velleman, narrows the gap between theory and practice, by covering relevant and real-life statistical methods that help business students make good, data-driven decisions. With their unique blend of teaching, consulting, and entrepreneurial experiences, this dynamic author team brings a modern edge to teaching statistics to business students. Focusing on stats in the context of real business issues, with an emphasis on analysis and understanding over computation, the text helps students to be analytical, prepares them to make better business decisions, and shows them how to effectively communicate results.
MyLab Statistics is not included. Students, if MyLab Statistics is a recommended/mandatory component of the course, please ask your instructor for the correct ISBN.
