An Introduction to Statistics
An Active Learning Approach

- Kieth A. Carlson - Valparaiso University, USA
- Jennifer R. Winquist - Valparaiso University, USA

The **Second Edition** takes a unique, active approach to teaching and learning introductory statistics that allows students to discover and correct their misunderstandings as chapters progress rather than at their conclusion. Empirically-developed, self-correcting activities reinforce and expand on fundamental concepts, targeting and holding students’ attention. Based on contemporary memory research, this learner-centered approach leads to better long-term retention through active engagement while* *generating explanations. Along with carefully placed reading questions, this edition includes learning objectives, realistic research scenarios, practice problems, self-test questions, problem sets, and practice tests to help students become more confident in their ability to perform statistics.

“The most impressive feature of the text is the manner in which it invites the student to interact with and digest the material covered in each chapter.”

This is perhaps the most student friendly intro to statistics book I've had the pleasure of reading. I work with students from the social sciences and before learning can begin, fear must be put to rest. This text presents statistical terms in small chunks to alleviate fear and even perhaps to begin a love affair with the language of statistics.
