List of Free Data Science Books

Many of the books in the excellent "Think" series have been made available for free by the author, Dr. Allen Downey at https://greenteapress.com/wp/

They are very short, informative books aimed at programmers to pick up the basics of probability and statistics.

Nice list. I would give them a try. There's a site for data science if you find useful:
