4434Rice Virtual Lab in Statistics
http://www.merlot.org/merlot/viewMaterial.htm?id=79148
Online statistics open textbook and additional resources to assist students in understanding of statistics. Topics covered include Analysis of Variance, Boxplot, Confidence interval, Contrast among means, Correlated t-test, Correlation, Histogram, Independent groups t-test, Regression, Repeated measures ANOVA, and t-test. The applets in the simulations, demonstrations, an d caste studiesare in the public domain and can therefore be used without restriction. Simulations and demonstrations and source code are available for download.

http://www.merlot.org/merlot/viewMaterial.htm?id=82840
This applet estimates and plots the sampling distribution of various statistics (i.e. mean, standard deviation, variance). You specify the population distribution, sample size, and statistic. An animated sample from the population is shown and the statistic is plotted. This can be repeated to estimate the sampling distribution.Simulations/Demonstrations in Statistics
http://www.merlot.org/merlot/viewMaterial.htm?id=75489
This Virtual Lab contains simulations for a variety of statistical concepts, including ANOVA, correlation, Regression, T-tests, Goodness of Fit, Histograms, etc. Each statistical topic can be searched and appropriate simulations or demonstrations are shown. Graphics that can be manipulated are shown, instructions are provided, and exercises are included. Links are also provided for definitions.Normal Approximation to the Binomial Distribution
http://www.merlot.org/merlot/viewMaterial.htm?id=79726
This Java applet demonstrates the use of a normal distribution to approximate a binomial distribution. Correction for continuity is automatically used. The parameters of the binomial can be specified, after which the binomial and approximating normal distributions are displayed graphicallyContingency Tables
http://www.merlot.org/merlot/viewMaterial.htm?id=627519
This applet simulates experiments using 2 x 2 contingency tables. You specify the population proportions and the sample size and examine the effects on the probability of rejecting the null hypothesis.Case Studies in Statistics
http://www.merlot.org/merlot/viewMaterial.htm?id=75491
Included at this site are a variety of case studies that demonstrate the use of statistics. One can search the type of statistic (ANOVA, t-test, regression) and find actual cases that used that particular concept. For each of the cases, background information is provided as well as a description of the experimental design, descriptive statistics, and inferential statistics. In some cases raw data is provided as well as graphs.Hyperstat Online Statistics Textbook
http://www.merlot.org/merlot/viewMaterial.htm?id=75488
This is an online statistics book with links to other statistics sources. The site provides a tutorial on a variety of statistical concepts, including univariate data, bivariate data, normal distribution, sampling distributions, etc. Within each lesson are links to definitions and other information.2 x 2 Contingency Tables
http://www.merlot.org/merlot/viewMaterial.htm?id=550936
This applet simulates experiments using 2 x 2 contingency tables. You specify the population proportions and the sample size and examine the effects on the probability of rejecting the null hypothesis.A small effect size can make a large difference
http://www.merlot.org/merlot/viewMaterial.htm?id=550938
This applet demonstrates that even a "small" effect can be important under some circumstances. Applicants from two groups apply for a job. The user manipulates the mean and the cut-off score in order to see the effects the small changes has on the number of people hired in each group. The effects on the proportion of hired applicants from each group are displayed.Online Statistics Education

'This is a collaborative effort led by David Lane of Rice University. The core material is an interactive textbook that is best used over the Internet to take advantage of the embedded questions created in JavaScript. The PDF version that can be downloaded simply shows the answers in a different font following the questions.An attractive feature of Online Statistics is the suite of case studies making use of the actual data from published studies in the scientific literature and popular media. The data sets for the case studies are provided as Excel files. The website also provides some computational tools running in the browser for the statistical calculations needed for the analysis of the case studies, although instructors may prefer to use free software such as R or software already available at their institutions.Also part of the course is a set of 31 simulations illustrating key concepts such as the meaning of a 95% confidence interval. Some are written in JavaScript and run without difficulty, but others are written in Java and may present a problem because of the security concerns surrounding Java applets running in browsers.'
