This site has an area for featured data sets and is constantly be updated by its users. In its About Us section Many Eyes proclaims that it "is a bet on the power of human visual intelligence to find patterns. Our goal is to "democratize" visualization and to enable a new social kind of data analysis. Jump right to our visualizations now, take a tour, or read on for a leisurely explanation of the project. " While its use is free Many Eyes does require "an alphaWorks Services Use Agreement" that spells our terms of use,copy right, liability, etc. Users must agree to terms and conditions.Wed, 16 Jun 2010 01:23:12 -0400Probability Plotter/Calculator

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2007AniWiki is a gallery for statistical animations in several subjects such as probability, linear models, multivariate statistics, and nonparametric statistics. Most of the animations are created in the R environment.Sun, 10 Jan 2010 10:01:45 -0500Sampling distribution of the mean
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1793
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1793This FLASH based applet illustrates the sampling distribution of the mean. This applet allows the user to pick a population from over 2000 pre-defined populations. The user can then choose size of the random sample to select. The applet can produce random samples in one, 10, 100, or 1000 at a time. The resulting means are illustrated on a histogram. The histogram has an outline of the normal distribution and vertical lines at 1, 2, and 3 standard deviations. The applet can be viewed at the original site or downloaded to the instructors machine.Sat, 26 Jan 2008 05:00:45 -0500Cartoon: Raking the Lawn

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1614
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1614Compared to probability calculators, the traditional format of distribution tables has the advantage of showing many values simultaneously and, thus, enables the user to examine and quickly explore ranges of probabilities. This webpage includes a list of distributions and tables, including the standard normal (Z) table, student's t table, chi-square table, and F distribution tables. An animation of the density function and distribution function is shown above each distribution table to demonstrate the effects changing degrees of freedom and significance levels have on the shape of a distribution.Mon, 23 Oct 2006 10:37:14 -0400Brownian Motion Applet

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1453
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=1453This applet demonstrates the Binomial distribution by simulating Galton's Board, dropping balls through a triangular array of nails. When a ball hits a nail, it has a 50 percent chance of falling to the left or the right. Because Galton's Board consists of a series of experiments, the piles under the board are the sum of n random variables, where n is the number of rows of nails on the board.Tue, 1 Aug 2006 03:16:50 -0400World Development Chart
