The authors have created a user-friendly set of online interactive dynamic tools called StatKey to illustrate key ideas and conduct computer-intensive analyses. The tools include options for displaying descriptive statistics (graphs and summary statistics) and apps for using normal and t-distributions as well as easy-to-use options for using simulation methods. These tools are fully integrated with the textbook, especially through WileyPLUS with icons that take students directly to activities.
