- Auto-graded Challenge Activities provide higher stakes evaluations
- Test Bank extends assessment opportunities
- Tintle’s six-step statistical exploration and investigation method is enhanced and reinforced through zyBooks’ interactive tools
- Optional chapter on probability included
- Designed with flexibility for on-campus, hybrid or fully online courses

## The zyBooks Approach

### Less text doesn’t mean less learning.

Built from the ground up using zyBooks’ pedagogy and in close collaboration with the authors, the Introduction to Statistical Investigations zyBook takes the authors’ spiral approach to the statistical process into a new experiential paradigm. Rather than passively reading along as the authors apply their approach to worked examples, students interact with zyBooks’ guided animations, simulation tools, and learning questions with answer-specific feedback.

By manipulating real-world data and drawing conclusions through these interactive tools, students become immersed in the process of “doing statistics,” which builds confidence and empowers success.
