Instructors and learners of statistics may be interested in the independent nonprofit OpenIntro, whose mission is to make educational products that are free, transparent, and lower barriers to education. Here, readers will find three introductory statistics textbooks that are well-suited for courses at the high school or college level. Two of them, OpenIntro Statistics and Advanced High School Statistics, were updated with new editions in 2019, while the third textbook, Introductory Statistics with Randomization and Simulation, was published in 2014. All three can be downloaded for free as PDF files, and each textbook also has a variety of supplementary content available, such as data sets, R packages, LaTeX files, online apps, and more. OpenIntro also offers practice labs for several statistical programs: R (and RStudio), SAS, and Stata, as well as numerous videos aligned to different sections of each textbook. Additionally, instructors can register with OpenIntro for free to gain access to extra resources like solutions to even-numbered exercises and sample exams. For anyone interested in learning statistical skills, OpenIntro is a valuable resource.
