Statistical Methods: An Introduction to Basic Statistical Concepts and Analysis, Second Edition

by Cheryl Ann Willard (Author)

This textbook is designed for students who have no prior training in statistics. It offers a solid foundation in core statistical concepts typically covered in introductory courses. The emphasis is on clear explanations of statistical constructs rather than mathematical proofs.

The book begins with an introduction to descriptive statistics, including measures of central tendency and variability. It then transitions smoothly into inferential statistics, covering topics such as z-scores, probability, and sampling distributions. These foundational chapters provide the necessary background for understanding hypothesis testing.

Hypothesis testing is taught through a four-step process that is consistently applied throughout the text, ensuring consistency in the learning experience. This approach includes detailed coverage of t tests, one- and two-way ANOVAs, chi-square, and correlation analyses. A chapter on nonparametric tests is also included as an alternative when parametric test assumptions cannot be met.

To enhance student understanding, each chapter contains “thought questions” and practice problems that integrate throughout the text. The book is structured to help students gradually master statistical concepts, making it a valuable resource for both classroom use and self-study.
