This application lets users upload a data set to use as a population from which samples can be drawn, or simulate a dataset from a wide variety of distribution.

The population distribution of the variable of interest (user's choice) is shown, and multiple samples created. For each sample, the value of a chosen test statistic is calculated. The distribution of this is then displayed as a histogram. This histogram can be build one sample at a time in an animated fashion, or the user can choose to skip ahead.
