Introduction to Modern Statistics is a re-imagining of a previous title, Introduction to Statistics with Randomization and Simulation. The new book puts a heavy emphasis on exploratory data analysis (specifically exploring multivariate relationships using visualization, summarization, and descriptive models) and provides a thorough discussion of simulation-based inference using randomization and bootstrapping, followed by a presentation of the related Central Limit Theorem based approaches. The second edition of IMS has updated datasets, additional exercises, a new application for chapter 3, and updated text and code to reflect changes in best practices. Other highlights include:

Web native book. The online book is available in HTML, which offers easy navigation and searchability in the browser. The book is built with the bookdown package and the source code to reproduce the book can be found on GitHub. Along with the bookdown site, this book is also available as a PDF and in paperback. Read the book online here.

Tutorials. While the main text of the book is agnostic to statistical software and computing language, each part features 4-8 interactive R tutorials (for a total of 32 tutorials) that walk you through the implementation of the part content in R with the tidyverse for data wrangling and visualisation and the tidyverse-friendly infer package for inference. The self-paced and interactive R tutorials were developed using the learnr R package, and only an internet browser is needed to complete them. Browse the tutorials here.

Labs. Each part also features 1-2 R based labs. The labs consist of data analysis case studies and they also make heavy use of the tidyverse and infer packages. View the labs here.

Datasets. Datasets used in the book are marked with a link to where you can find the raw data. The majority of these point to the openintro package. You can install the openintro package from CRAN or get the development version on GitHub. Find out more about the package here.

We are in the process of updating to the 2nd Edition, with the main PDF on Leanpub now reflecting the new edition as well as the HTML and paperback are now available in the 2nd Edition. The 1st Edition PDF may be found with the free "Extras" when purchasing the PDF through the link below on Leanpub (including "purchases" for $0), and other 1st Edition links are also available below.

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.

Restricted to Verified Teachers only. The sample exams currently available are from our other textbooks. We plan to add sample exams for IMS soon.

These videos give a taste of what statisticians, also known as data scientists, do in the real world.

This section is for content not covered in IMS that might be of interest to a subset of instructors. For example, some courses require Probability as a topic covered, and so we are providing an online-only supplement to support such a scenario.
