Every day we have to make decisions about uncertain events like, 'Is that my phone ringing or one on the television?', or, 'Is the person talking to me telling the truth?' In this tutorial, you will...

The SOCR Modeler allows the user to compare data with typical statistical models such as the beta distribution, exponential, gamma, Poisson, etc. The user can adjust the bin ranges for the data...

This site has a collection of computational tools for several basic statistical procedures including: probabilities, Binomial, Bayes, Poisson, Chi-Square, t-distribution, F-distributions, Normal...

This activity makes use of a campus-based resource to develop a "capstone" project for a survey sampling course. Students work in small groups and use a complex sampling design to estimate the number...

This applet simulates experiments using 2 x 2 contingency tables. You specify the population proportions and the sample size and examine the effects on the probability of rejecting the null...

This applet demonstrates that even a "small" effect can be important under some circumstances. Applicants from two groups apply for a job. The user manipulates the mean and the cut-off score in order...

This online resource is intended to help students understand concepts from probability and statistics and covers many topics from introductory to advanced. You can follow the progression of the text...
