### Table of Contents

"Weiers definitely is the best. The shorter chapter sections are the right length for our students. The author writes in clear and lucid prose, and is not "over their heads." This is the best book (out of five total) I have used in my fourteen years of teaching undergraduate statistics for business majors.""Overall, I like the quantity and quality of the exercises. I think this is the real strength of this textbook. Good coverage of basic statistics; chapters are well-written and easy to read/understand; great exercises.""I like the manner in which the material is introduced and explained through both the text and illustrations...""The book is well-written and easy to read.
