Provide an interactive introduction to the growing field of statistics with zyBooks

Statistics for Decision Making covers descriptive and inferential techniques, probability theory, and prediction using linear models.

  • Examples using Microsoft Excel are provided to build practical skills in statistics
  • Interactive applets are used to aid conceptual understanding
  • Participation activities and challenge activities use real-world datasets to illustrate statistical techniques
  • Case studies exemplify the statistical analysis process from start to finish
  • Adopters have access to a test bank with questions for every chapter

What is a zyBook?

Statistics for Decision Making is a web-native, interactive zyBook that helps students visualize concepts to learn faster and more effectively than with a traditional textbook. (Check out our research.)

Since 2012, over 1,700 academic institutions have adopted web-native zyBooks to transform their STEM education.

zyBooks benefit both students and instructors:

  • Instructor benefits
