Distribution of the Sample Sum, Sample Mean, Sample Variance, and Sample Chi-Squared

This applet, created by Philip B. Stark of the University of California, Berkeley, illustrates this concept of the sampling distribution of a statistic by simulating the sampling distribution of the sample sum, mean, variance, and chi-square. Users can choose from a normal or uniform population or can supply their own data. Relevant statistics from each sample are calculated.
