title	OpenIntro Companion Activities
description	This is a homepage for a collection of interactive, browser-based activities to accompany an introductory level applied statistics course. The activities loosely follow the OpenIntro Statistics textbook from the folks at OpenIntro.org. Currently, the activities are written to leverage the R computing language. Additional versions which leverage Excel/Google Sheets and Python are forthcoming.

You'll find a growing list of Quarto-Live activities in the sections below. Ultimately, this project will provide a collection of activities covering a full introductory experience in applied statistics from several different domain disciplines (psychology, biology, sport, etc.) and with several different supporting software tools. Versions of all notebooks utilizing the R computing language are available, with corresponding versions in Excel and Python forthcoming.

These resources are open-sourced and will always remain freely available. If you are benefiting from using these activities and would like to support the their maintenance and the development of future resources, consider donating via the link below.
