Statistical applets  
This collection of of Java applets comes from NWP Associates, Inc. Datasets up to 100 rows, 10 columns can be analyzed for free; anything larger requires a subscription (Distributions, Probability & Stochastic Processes, Statistics and others).

Statistical Tables  
Need Statistical tables? Just point to the URL above and your audience can use them. Code can be downloaded, although I would advise you to wait for my newer version. The current version is not a full "Literate program", it is only semi-literate. This page contains a few of the applets developed in JAVA. The graphical stuff is based on Leigh Brookshaw's Graph2D class. The complete code is available if you are interested.

Statiscope  
Statiscope presents summarizing data and descriptive statistical charts. In the applet you can enter data manually or download data over the Internet. Charts included: Distribution, Probability mass, Density, Box plot, Stem & leaf. Other features such as hypothesis testing and calculation of confidence intervals are also included. The user interface is responsive and friendly, e.g. Statiscope introduces a new funny way of changing the scale. It is intended both for people learning the concepts of statistics and for practical use by researchers of various kinds... Statiscope is also available as a standalone application that has Open and Save menu options.

Chisquare  
This applet lets you calculate the chisquare statistic for a simple table, then simulate the chisquare statistic to estimate the P-Value.

Normal Probabilities  
This is a more interactive applet than the previous one; it allows the user to drag the ends of the included region with the mouse. This applet is more fun but its accuracy is limited by the resolution of the screen. However, it may be more educational because the user directly experiences the connection between the shaded area under the normal distribution and the probability.

Correlation  
This is a "Guessing Correlations" applet: you press the button. Four scatter plots should appear. Your job is to match the plots with the correlations. Choose which plot you think goes with each correlation, then you can see the answers.

Brownian motion 3  
In this simulation particles begin a 60-step random walk from the origin. The x-values at the end of the walk are tallied, and a running frequency graph is displayed. This graph tends towards a fixed limit as the number of trials increases: the famous Gaussian distribution (aka, the infamous Bell curve).

z-scores  
Use to answer all questions which specify a probability and ask for the relevant range of raw or z-scores. Also does transformations between raw scores and z-scores in either direction.

Normal Approximation to Binomial  
The initial graph shows the probability distribution associated with flipping a fair coin 12 times defining a head as a success. The vertical lines represent the probabilites of obtaining each of the 13 possible outcomes (0-12 heads).

Normal Tables  
This applet illustrates how to use "old-fashioned" tables of normal probabilities. This applet is sometimes tempermental and requires a tall browser window.

Central Limit Theorem Applet  
This applet demonstrates the central limit theorem using simulated dice-rolling experiments. An "experiment" consists of rolling a certain number of dice (1-5 dice are available in this applet) and adding the number of spots showing.

New Confidence Interval Applet  
This applet is designed to help students understand confidence intervals. Each of the 50 lines on the graph represents a confidence interval for the mean (assuming known variance).
