Students will be introduced to the Central Limit Theorem by letting them explore sample distributions. By changing sample size, they observe the effect on distributions of sample means. First, students investigate the idea of a random sample. Second, they look at histograms made from sample means of various sizes. Finally, students use a slider to control the sample size, and watch the shape of the sampling distribution change as the size of the sample changes.
