OpenIntro Statistics

Diez, Barr, Cetinkaya-Rundel
 
The OpenIntro project was founded in 2009 to improve the quality and availability of education by producing exceptional books and teaching tools that are free to use and easy to modify. The inaugural effort is OpenIntro Statistics. Probability is optional, inference is key, and we feature real data whenever possible.

Supplements:
  • MyOpenMath online homework. MyOpenMath is a free online homework system, built on the open source IMathAS assessment platform. It provides randomized, algorithmically generated homework with automated grading of numerical and algebraic answers, similar to WebAssign and MyMathLab. It also provides a course management system with gradebook, file posting, discussion forums, etc. Assessment sets have been created for this textbook, which may be available for self-study by students, or can copied as a starter course shell by faculty.

    MyOpenMath use is a provided free by Lumen Learning. Community support may be available through faculty support forums. For direct support, course development and support service contracts are available from Lumen.

    For Washington State faculty, the WAMAP.org site also mirrors this content.
  • Videos. See the comments below for details.
  • CourseWare package. Courseware packages typically include a course structure with syllabus, some form of homework assignments, and some type of assessments. They may also include: videos, lecture notes, handouts, worksheets, quizzes, etc. See comments below for details
Notes: There are videos and slides for some sections and some R-based labs on their website.
