A new book, Introduction to Modern Statistics (IMS is available on the web, as a PDF, and in paperback), represents the evolution of Introductory Statistics with Randomization and Simulation (ISRS). For those who are considering adopting Introductory Statistics with Randomization and Simulation, we recommend Introduction to Modern Statistics instead.

There aren't any immediate plans for material changes to ISRS or its distribution, though this book is now de-emphasized in our catalog, e.g. moved to last in our list of books available. We are starting to think about what the right distribution changes, if any, might be as we encourage people to move towards IMS, but it's too early for us to consider implementing any such changes. The earliest we would consider any major change is mid-2022, and even then, we intend to proceed with caution to minimize disruptions. If you do have direct feedback or thoughts, such as what would be useful to you to switch to IMS -- or why that isn't something you want to do -- we appreciate the feedback through our Contact page.

Amazon KDP is raising print prices by ≈40% in mid-June. As a result, we will be raising this book's B&W paperback price to  to $25 to align with our other textbooks and compensate for the increased costs. Despite the price increases on the OpenIntro titles, and while this book will be seeing a larger increase than the other books, we expect margins net our costs to decrease our overall OpenIntro operating margins. That is, in total, the many tens of thousands of dollars that students will pay for these price increases each year will benefit Amazon, not OpenIntro, and OpenIntro will likely lose money on net revenue/costs as a result of these price changes. As a result of this change, we are also more aggressively exploring alternative printers to Amazon that provide better quality books as well as selling more books outside of Amazon.

Videos and slides are shared across books. Don't fret if you see a different section number than the one you expect: check the title and you'll see it is covering the topic of interest.
