Full Description
For Introductory Statistics-Algebra-based courses. This text offers a straightforward, "nuts and bolts", introduction to statistics. The explanations are clear and simple and minimize calculations where possible. A diverse range of applications and examples are presented to make the materials appealing to a wide range of students. The Eighth Edition features new problems, more real data based examples and exercises, and fuller integration of technology.
