They don’t share a great deal about the who, why and how of this free online statistics textbook. Normally, that would make me question including it here on The Free Textbook List. However, what we do know is that this is a collaborative online textbook from The Australian National University. I suspect this text is the work of a number of students and educators and is high quality reference for students. It includes online quizzes to help reinforce topics presented.
