Build confidence and mastery with enhanced Psych Stats Achieve tools.

In this innovative text, pioneering educators Gary W. Lewandowski, Jr. (Discovering the Scientist Within) and Kevin P. McIntyre (creator of Open Stats Lab) help students overcome math anxiety while building essential statistical skills. Each chapter follows a distinctive two-part approach, introducing core concepts through engaging real-world questions before diving into a more rigorous, in-depth scenario.

The Achieve update for Behavioral Statistics delivers a more flexible, supportive learning experience for today’s diverse classrooms. Designed for students with varying levels of math preparedness, the course emphasizes strong assessment alongside targeted remediation.

New for Fall 2026: AI Tutor & Algorithmic Content Gain flexibility with expanded, reusable algorithmic question sets. Our new math readiness assessment and AI Tutor work in tandem to provide real-time, targeted remediation. Students get the guidance they need on individual problems—without being given the answers.

To deepen conceptual understanding, Data Lab activities incorporate real datasets, offering meaningful opportunities for interpretation, application, and real-world relevance.

Additional enhancements—including LearningCurve integration and improved course organization—create a more consistent, streamlined experience across Behavioral Statistics titles.
