OpenIntro was started with one goal in mind: create a free and open-source introductory textbook. 

The mission of OpenIntro is to make educational products that are free, transparent, and lower barriers to education..  

There are free statistics textbooks, plus labs, videos, data sets, code, lecture slides and more.
