This site presents workbook-style, project-based material that emphasizes real world applications and conceptual understanding. This material is designed to give students a sense of the importance and allure of statistics early in their college career. By incorporating many of the successful reforms of the introductory statistics course into a wide range of more advanced topics we hope that students in any discipline can realize the intellectual content and broad applicability of statistics.

The complete text is designed for use in a one- or two-semester course in statistics that presents a broad collection of statistical methods currently used in the natural and social sciences. An individual chapter can be used as a final project in an introductory statistics course or the chapters can be combined to form a second statistics course. A selected subset of these chapters can also serve as supplementary materials in your existing courses on topics such as regression analysis, methods for categorical data, or the design of experiments.  

The Table of Contents below indicates any known dependencies between chapters in italics. The text is highly adaptable in that the various chapters/parts can be taken out of order or even skipped to customize the course to your audience. Please note the Project and Advanced Lab in each chapter relies on concepts presented in the Introductory Lab. Since this is a work in progress, please feel free to contact Dr. Shonda Kuiper for the most recent versions. Materials for the following chapters are currently written:

Each chapter is written in a workbook style with the intention that students will progress through much of the material on their own. Depending on the level of in-class active learning, group work, and discussion that you prefer in your course, some of this work might occur during class time and some outside of class. Although not necessary, you may choose to expand on a particular topic by supplementing with your own lecture notes or working through one of the exercises as an example before students attempt the material on their own. Note that at least some class time will certainly be needed to discuss the chapters as students progress.

The Advanced Lab is optional and provides several additional exercises and more in-depth coverage than the Introductory Lab.  Some Advanced Lab sections that require a stronger background in mathematics are clearly marked throughout the text.

Clearly one chapter on a statistical topic covers the material in less depth than a dedicated course on that topic, but that is not our intent. Exposure to a broad set of topics and methods will give students a solid foundation when they are expected to analyze data in their future careers. We believe that this text will have broad appeal and application, allowing students to see the many exciting possibilities within the discipline of statistics.  

PREREQUISITS: These materials are accessible to students who have taken a one-term, algebra-based introductory statistics course, such as a high school advanced placement statistics course. The text assumes a rudimentary knowledge of the concepts of hypothesis testing and confidence intervals and familiarity with statistical inference by t- and z-procedures; however, these topics are often briefly reviewed when referenced in the text.
