## Description

**Introduction to the Design & Analysis of Experiments** introduces readers to the design and analysis of experiments. It is ideal for a one-semester, upper-level undergraduate course for majors in statistics and other mathematical sciences, natural sciences, and engineering. It may also serve appropriate graduate courses in disciplines such as business, health sciences, and social sciences. This book assumes that the reader has completed a two-semester sequence in the application of probability and statistical inference.

CourseSmart textbooks do not include any media or print supplements that come packaged with the bound book.
