Introductory Statistics is written for a one- or two-semester first course in applied statistics.
This book is intended for students who do not have a strong background in mathematics. The
only prerequisite for this text is knowledge of elementary algebra.
Today, college students from almost all fields of study are required to take at least one
course in statistics. Consequently, the study of statistical methods has taken on a prominent
role in the education of students from a variety of backgrounds and academic pursuits. From
the first edition, the goal of Introductory Statistics has been to make the subject of statistics
interesting and accessible to a wide and varied audience. Three major elements of this text
support this goal:
1. Realistic content of its examples and exercises, drawing from a comprehensive range of ap-
plications from all facets of life
2. Clarity and brevity of presentation
3. Soundness of pedagogical approach
These elements are developed through the interplay of a variety of significant text features.
The feedback received from the users of the sixth edition of Introductory Statistics has
been very supportive and encouraging. Positive experiences reported by instructors and stu-
dents have served as evidence that this text offers an interesting and accessible approach to
statistics—the author’s goal from the very first edition. The author has pursued the same goal
through the refinements and updates in this seventh edition, so that  Introductory Statistics
can continue to provide a successful experience in statistics to a growing number of students
and instructors.
