WebCab Probability and Statistics (J2SE Edition) 

This suite consists of four packages: Statistics, Discrete Probability, Standard Probability Distributions, Hypothesis Testing, Correlation and Linear Regression. Submitted: Sep 19, 2004

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). Submitted: Nov 02, 1999

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 semiliterate. 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. Submitted: Nov 01, 1999

Gambler's Ruin 

Gambler's Ruin is a famous problem in statistics. This applet lets you view it. Source code is avialable. Submitted: Nov 02, 1999

Regression 

After putting points on the graph area the correlation coefficient, regression line and residuals are computed and displayed. Submitted: Nov 03, 1999

Statistics Online Computational Resource 

A suite of Java tools for education and statistical computing. The SOCR resource includes: Distribution modelers, experiments, games, analysis and additional Java GUIbased tools. Submitted: Aug 05, 2005

LeastSquares fitting of data 

This applet determines a linear or polynomial function that is leastsquares fitted to a discrete set of data points. Functions of one variable can be plotted. Submitted: Nov 11, 2001

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. Submitted: Nov 02, 1999

Sampling Distribution Simulation 

This Java applet lets you explore various aspects of sampling distributions. When the applet begins, a histogram of a normal distribution is displayed at the topic of the screen. Submitted: Nov 02, 1999

Chisquare 

This applet lets you calculate the chisquare statistic for a simple table, then simulate the chisquare statistic to estimate the PValue. Submitted: Nov 03, 1999

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. Submitted: Nov 02, 1999

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. Submitted: Nov 03, 1999

Log Statistics 

This document has the following sections: Statistics Files, Sorting Statistics, Charting Statistics, Displaying Statistics, Buttons. The Log Statistics page allows you to sort and display service log data in several ways. Submitted: Nov 02, 1999

Brownian motion 3 

In this simulation particles begin a 60step random walk from the origin. The xvalues 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). Submitted: Nov 02, 1999

zscores 

Use to answer all questions which specify a probability and ask for the relevant range of raw or zscores. Also does transformations between raw scores and zscores in either direction. Submitted: Nov 02, 1999

Rice Virtual Lab in Statistics 

Java applets that demonstrate various statistical concepts. Submitted: Nov 01, 1999

Galton's quincunx 

This applet simulates Galton's Board, in which balls are dropped through a triangular array of nails. This device is also called a quincunx. Submitted: Nov 02, 1999

Interactive Statistics Pages 

Some Experimental Interactive Statistics Pages at UIUC. Submitted: Oct 30, 1999

Power of a Hypothesis Test Applet 

This applet illustrates the fundamental principles of statistical hypothesis testing through the simplest example: the test for the mean of a single normal population, variance known (the Z test). Submitted: Nov 02, 1999

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 (012 heads). Submitted: Nov 02, 1999

Normal Tables 

This applet illustrates how to use "oldfashioned" tables of normal probabilities. This applet is sometimes tempermental and requires a tall browser window. Submitted: Nov 02, 1999

Brownian motion 3b 

In this simulation particles begin a 60step random walk from the origin. The xvalues 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). Submitted: Nov 02, 1999

Central Limit Theorem Applet 

This applet demonstrates the central limit theorem using simulated dicerolling experiments. An "experiment" consists of rolling a certain number of dice (15 dice are available in this applet) and adding the number of spots showing. Submitted: Nov 02, 1999

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). Submitted: Nov 02, 1999

Brownian motion 1 

In 1827 the English botanist Robert Brown noticed that pollen grains suspended in water jiggled about under the lens of the microscope, following a zigzag path. you can view a simulation of this in this applet. Submitted: Nov 02, 1999

A "Small" Effect Size Can Make a Large Difference 

Each applicant for a job is given a series of tests and interviews from which a numerical "suitability" score is calculated. This score is designed to predict success on the job and is used as the criterion for selecting applicants. Submitted: Nov 03, 1999

Leverage points 

This applet shows effect of leverage points on the regression line. Submitted: Nov 03, 1999

IDD Statistics Viewer 

This Java applet is an interactive IDD Latency Statistics Server. Submitted: Nov 02, 1999
