This site, created by the Department of Statistics at Yale University gives an explanation, a definition and an example of conditional probability. Topics include the probabilities of intersections of events and Bayes'...

This lesson is based on several interesting problems. Each problem has a somewhat unexpected answer; in fact, many people have a hard time accepting experimental results for these problems, as the results may seem...

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,...

This site, presented by the Department of Statistics at Yale University, gives an explanation of, a definition for and an example of confidence intervals. It covers topics including inference about population mean and z...

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...
