## Sampling Distribution of the Mean

This flash program shows the consistency of sample means from variously shaped populations. A student can change sample sizes, view raw data, choose samples singly or by the thousands, and observe changes as the sample numbers and populations change. It is also available as a stand-alone program (recommended for the classroom as it can be shown in full screen mode).
