Given a sample of N values of X randomly drawn from a normally distributed population, this program will calculate the .95 and .99 confidence intervals (CI) for the estimated mean of the population. Data entry is simple,...

The applets in this section of Statistical Java allow you to see how levels of confidence are achieved through repeated sampling. The confidence intervals are related to the probability of successes in a Binomial...

This applet, created by Ivo Dinov of the University of California at Berkeley, introduces the concept of confidence intervals. Select an alpha level, sample size, and the number of experiments, and click "Play." For...
