Show HN: I wrote an introductory data science book (opens in new tab)

Hi all,

After 3.5 years of writing I have released a book about introductory data science.

The book is available for free on the website, and there is a link there to purchase a print copy.

The book is a introductory reimagining of what data science could be. It develops and applies a principled, tested, reproducible, end-to-end workflow that focuses on quantitative measures in and of themselves, and as a foundation to allow students to explore questions that are of interest to them.

I would appreciate your feedback.
