Sampling Distribution Programs

Here are four programs that demonstrate sampling distributions. For each one, a "population" of 20,000 elements is established. The user selects a sample size and random samples are drawn from the population. Both the population and the samples are graphically shown on the screen. The appropriate sample statistics and estimates of the relevant standard error are calculated for each sample. When the program is instructed to draw a large number of samples, you can see the development of the beginnings of a sampling distribution.


There are programs for sampling distributions of sample means, difference between sample means, sample proportions, and sample correlations.
