View Resource Binomial Calculator

Students can change the binomial parameters n and p and see the effect on a bar plot representing the binomial probabilities.
View Resource Binomial Histogram

This Binomial applet allows the user to adjust the n and the p and see the resulting histogram. There is also an option to overlay the normal distribution over the histogram. The "Area from" and...
View Resource Binomial Probabilities

The page will calculate the following: Exact binomial probabilities, Approximation via the normal distribution, Approximation via the Poisson Distribution. This page will calculate and/or estimate...
View Resource Binomial Proportions

This calculator computes the probability that two proportions are equal, given sample proportions. The user inputs values for x1, n1, x2, and n2. The null hypothesis is that the two proportions are...
View Resource - Statistics made easy

BrightStat is a free online application for statistical analyses. Besides many non-parametric tests, BrightStat offers multiple linear regression, logistic regression, ANOVA and repeated measurements...
View Resource Building a Probability Tree

This applet simulates a probability tree diagram. Step 1: Click inside the appropriate box on the desired level to build the tree. Step 2: Click on "Set Probabilities" at the top. Step 3. When...
View Resource Central Limit Theorem

Illustrates the central limit theorem by allowing the user to increase the number of samples in increments of 100, 1000, or 10000.
View Resource Chebychev's Estimate

For n = 50 to 400, in steps of size 5, this program computes and displays (1) the exact probability P(|A_n - p| >= epsilon), where A_n is the average outcome of n Bernoulli trials with probability p...
View Resource Chi Square Calculator

This applet calculates probabilities from a chi-square distribution. Enter the degrees of freedom and either the critical value (in the "Area right of" box) or the probability (in the "=" box). ...
View Resource Chi-Square

This page will calculate the value of chi-square for a one- dimensional "goodness of fit" test, for up to 8 mutually exclusive categories labeled A through H. To enter an observed cell frequency,...
