This page, created by Professor Ivo Dinov of the University of California Berkeley, provides a table of chi-square distribution probabilities with degrees of freedom 1-45. This page was created as a reference tool for...

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 applet lets you take "slices" through a multivariate data set to compare the distribution of a variable without regard for the values of the other variables with the distribution of that variable when the value of...

This tutorial, created by Thomas W. MacFarland of Nova Southeaster University, describes various measures of central tendency, their theory and use, and demonstrates them with an example on final exam scores. Data sets...

This online, interactive lesson on distributions provides examples, exercises, and applets which explore the basic types of probability distributions and the ways distributions can be defined using density functions,...
