Very easy to use. Clearly illustrates the relationship between the target population, the sample, and the sampling distribution. The animation helps students keep the sampling process more firmly in mind. The user can easily vary the target population to show that the Central Limit Theorem holds for an arbitrary target population. Also, it was much easier to use than other applets I found because you do not have to stop to type in numbers. The user can select different distributions, sample sizes, and numbers of samples easily with the mouse.I used the applet in my classroom to solidify the concepts I had already introduced through an actual sampling exercise in which each student brought a sample of 10 coins to class. We computed the mean of each sample together and I found it helped to have the applet to refer to the example and vice-versa. This applet is by far the best I was able to find on this topic, and will certainly enhance learning and teaching.
