Introduction to Statistical Investigations leads students to learn about the process of conducting statistical investigations from data collection, to exploring data, to statistical inference, to drawing appropriate conclusions. The text is designed for use in a one-semester introductory statistics course and focuses on on genuine research studies, active learning, and effective use of technology. Presented throughout the text are simulation and randomization tests to introduce students to statistical inference, yielding a strong conceptual foundation that bridges students to theory-based inference approaches. This approach allows students to see the logic and scope of inference in the first chapter and to cycle through these ideas, too often lost to introductory statistics students, repeatedly throughout the course. Introduction to Statistical Investigations follows the GAISE recommendations endorsed by the American Statistical Association.
