Confidence Interval  Confidence intervals (.95, .99) for various samples from a single sampling distribution are displayed.  Confidence Interval 
Correlation  View and compare scatterplots for different magnitudes of correlation. See how changes in the scatterplot impact on the calculation of coefficients.  Correlation/Regression 
Data Generator  Generate sample data that conforms to userdefined population parameters. The sample data then can be cut and pasted into other applets (i.e., correlation and regression) for further analysis.  Frequency distribution 
Effect Size  This applet can be used to demonstrate that even a "small" effect can be important under some circumstances.  Effect Size 
Normal Distribution  Under the assumption of a standard normal distribution of scores, see how probabilities can be attached to specific occurrences within the distribution to address questions of the form "How likely is it to be the case that ...?"  Normal Distribution 
Probability  Illustrate concepts (theoretical  empirical) underlying binomial and normal distributions.  Probability 
Sampling Distributions  This Java applet lets you explore various aspects of sampling distributions.  Sampling Distribution
