WebAssign, the independent online homework and assessment solution, is proud to support the open source teaching community. Introductory Statistics 1st edition, authored by Barbara Illowsky and Susan Dean of De Anza College, is available through OpenStax and is now supported by homework questions and student learning resources within WebAssign.

Features
  • Every WebAssign question links to applicable chapters in a fully integrated eBook.
  • Lecture videos by Introductory Statistics author Barbara Illowsky.
  • Labs (Lab) – New for Spring 2021! Students can perform real statistical analysis in class or online with premade and module-specific Stats Labs. Require students to use the instructor-selected data analysis tool to analyze a real data set, pulling together knowledge learned from that module and previous material to facilitate whole-picture learning.
  • PowerPoint slides based on the extensive illustrations from the textbook.
  • Over 400 end-of-chapter problems direct from the text suitable for homework, review, and tests.
  • Practice Another Version which let students try another version of the question if they get stuck or need some extra practice.
  • Socratic feedback for most questions provides a student-centric approach to learning, challenging students to develop their critical thinking skills, and guiding them to the correct answer.
