This learning resource is built upon the online textbook, Introductory Statistics, available free of charge from OpenStax University. The textbook material, itself, is provided in the PDF format. This means you should have a PDF reader, such as Acrobat Reader. It is available here for downloading, free of charge--tap the Acrobat Reader image to begin the installation process.

Note: This e-textbook has over 900 pages of text and images. The first time you access this book, the downloading time might seem excessively long -- depending upon the speed of your Internet connection. Once the file is cached in your browser, however, loading times for individual assignments are much shorter.
