What is SOCR?
The goals of the Statistics Online Computational Resource (SOCR) are to design, validate and freely disseminate knowledge. Our Resource specifically provides portable online aids for probability and statistics education, technology based instruction and statistical computing. SOCR tools and resources include a repository of interactive applets, computational and graphing tools, instructional and course materials.

What are the main SOCR Components?
The core SOCR educational and computational components include: Distributions (interactive graphs and calculators), Experiments (virtual computer-generated analogs of popular games and processes), Analyses (collection of common web-accessible tools for statistical data analysis), Games (interfaces and simulations to real-life processes), Modeler (tools for distribution, polynomial and spectral model-fitting and simulation), Graphs, Plots and Charts (comprehensive web-based tools for exploratory data analysis), Additional Tools (other statistical tools and resources), SOCR Wiki (collaborative Wiki resource), Educational Materials and Hands-on Activities (varieties of SOCR educational materials), SOCR Statistical Consulting and Statistical Computing Libraries.

Java Browser Issues

As of Spring 2020, Internet Explorer (IE) is one of the very few browsers that support front-end Java-applets on client machines. Using EI to run SOCR Java Applets requires adding "" and "" to the Exception Site List managed in the Java Security tab, see Find the Java Control Panel. The Exception Site List is shown in the tab, and the SOCR URL's have to be added to the list to allow the SOCR Java Applets to run in the browser. See these instructions.

Chrome browser users need to explicitly allow Java applets to run in the browser window. This is accomplished by manually enabling the NPAPI plugins (chrome://flags/#enable-npapi).

How to use the SOCR Resources?
There are three major types of SOCR users: educators, students and tool developers. Course instructors and teachers will find the SOCR class notes and interactive tools useful for student motivation, concept demonstrations and for enhancing their technology based pedagogical approaches to any study of variation and uncertainty. Students and trainees may find the SOCR class notes, analyses, computational and graphing tools extremely useful in their learning/practicing pursuits. Model developers, software programmers and other engineering, biomedical and applied researchers may find the light-weight plug-in oriented SOCR computational libraries and infrastructure useful in their algorithm designs and research efforts. The three types of SOCR resources are:
  • Interactive Java applets: these include a number of different applets, simulations, demonstrations, virtual experiments, tools for data visualization and analysis, etc. All applets require a Java-enabled browser (if you see a blank screen, see the SOCR Feedback to find out how to configure your browser).
  • Instructional Resources: these include data, electronic textbooks, tutorials, etc.
  • Learning Activities: these include various interactive hands-on activities.
  • SOCR Video Tutorials (including general and tool-specific screencasts).
SOCR Support
Please consider making donations of any size to support SOCR student stipends (for  resource development and conference travel) and instructor-training/continuing-education  workshops (travel and stipends for K-16 educators to attend annual SOCR-events).
