OpenIntro Statistics
OpenIntro Statistics is a dynamic take on the traditional curriculum, being successfully used at Community Colleges to the Ivy League
OpenIntro Statistics is recommended for college courses and self-study.
Getting Started
Amazon KDP raised book print prices by ≈40% in 2023. These changes will net Amazon over $50,000 per year from sales on OpenIntro books, and we expect that OpenIntro will lose money as a result of reduced sales. We are continuing to explore alternative printers to Amazon that provide better quality books as well as selling more books outside of Amazon.
All of our website / resource links to Amazon are affiliate links. When you shop on Amazon using these links, we receive a small commission at no extra charge to you.
FREE -- OpenIntro Statistics PDF
If you want to skip the optional contribution, set the price to $0
$25 -- B&W paperback
Available on Amazon and in select bookstores
$26.74 -- Color paperback (sometimes discounted)
The current price is royalty-free. We plan to increase that price soon to $40 ($5.28 royalty to OpenIntro). This change is due to a slowing of voluntary contributions by PDF downloaders.
FREE -- Book PDF Best for Screen Readers
More detailed table of contents, extra text to ease aid navigation (e.g. explicitly noting when an example starts and ends), and "alt text" for all images. Note that page numbers do *not* alignn with the original PDF, so please use section, figure, example, et al numbers for referencing and navigation. Please send feedback via the openintro.org/contact page.
