Welcome to the SAGE edge site for An Introduction to Statistics, Second Edition.

The SAGE edge site for An Introduction to Statistics by Kieth A. Carlson and Jennifer R. Winquist offers a robust online environment you can access anytime, anywhere, and features an impressive array of free tools and resources to keep you on the cutting edge of your learning experience.


The Second Edition takes a unique, active approach to learning introductory statistics that allows students to discover and correct any of their misunderstandings as chapters progress rather than at their conclusion. Empirically-developed, self-correcting activities reinforce and expand on fundamental concepts, targeting 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 do statistics. 


We gratefully acknowledge Kieth A. Carlson and Jennifer R. Winquist for writing an excellent text and creating the materials on this site.
