Free Introductory Statistics Notes, Activities, and Solutions
Teaching
I have a license to teach mathematics at the secondary level in the state of Minnesota.
As an instructor of introductory statistics, I prepared these class notes as a review of the chapters in Elementary Statistics (4th Edition) by Navidi and Monk . They also draw from Workshop Statistics: Discovery with Data by Rossman and Chance . These materials include notes, worked examples, in-class activities, and solutions.
Use the sections below to find materials by topic. Each unit can be expanded or collapsed to make the page easier to browse.
