Highly praised for its clarity and great examples, Weiers's text takes an informal, student-oriented approach to fundamental statistical concepts. Non-technical terminology is used to describe statistical concepts, which are presented in the context of contemporary applications and student experience. Realizing that many business students are intimidated by this course, Weiers provides numerous learning aids and interesting applications drawn from real-world experience common to many students.
