What You’ll Find In This zyBook:
More action with less text.
- An exceptionally student-focused introduction to applied statistics.
- Traditionally difficult topics are made easier using animations and learning questions.
- Several chapters on data analytics are included.
- R coding environments are provided throughout to allow students to experiment.
- Commonly combined with “Applied Regression Analysis” with numerous configurations possible.
The zyBooks Approach
Less text doesn’t mean less learning.
This zyBook provides a concise introduction to bivariate and multivariate statistics using an applied approach with real-world data. Equations for common statistical quantities are provided, but most concepts are explained using animations rather than rigorous mathematical proof. This content is recommended for STEM majors who may not have a solid foundation on statistics, but want a friendly introduction to data analytics. R coding environments are provided that allows students to experiment with datasets that are both interesting and relevant to students’ day-to-day lives.
