This page, created by Ivo Dinov of the University of California, Berkeley, helps readers know which statistical tests are appropriate for the different types of data. Two charts display the information. A discussion of study design and sample size, as well as exercise questions with solutions are also provided. This is a great reference tool for anyone interested in different statistical tests and methods.

This applet, created by Ivo Dinov of the University of California at Berkeley, introduces the concept of confidence intervals. Select an alpha level, sample size, and the number of experiments, and click "Play." For each sample, the applet will show the data points as blue dots and the confidence interval as a red, vertical line. The true population mean is shown as a horizontal purple line, and green ovals indicate which intervals do not contain the true mean.

This applet, created by Ivo Dinov of the University of California, Los Angeles, demonstrates the normal approximation to the Poisson distribution. Users can set the rate, lambda, and the number of trials, n, and observe how the shape of the distribution changes. The Poisson distribution is shown in blue, and the Normal distribution is shown in red.

This applet, created by author Ivo Dinov of the University of California, Berkeley, allows users to input their own data and perform one and two-way analysis of variance (ANOVA). This interactive resource requires Java to be enabled. If not, the program will not load properly. This is a nice tool for either teachers or students interested in statistics, and more specifically, variance testing.

This applet, created by Ivo Dinov of the University of California, Berkeley, demonstrates the Central Limit Theorem. First, select a distribution (normal, uniform, skewed, custom) and add or delete data points by clicking on the graph. Then, sample from the parent population and the distribution of the sample mean is shown. Users can also choose to see the distribution of the median, standard deviation, variance, and range.

This page, created by Ino Dinov of the University of California, Berkeley, provides distribution calculators for the binomial, normal, Student's T, Chi-square, and Fisher's F distributions. Users set the parameters and enter either the probability or the test statistic and the calculators return the missing value. This is a simple, yet effective, statistical tool for instructors and students.

This applet allows users to run experiments such as Ball and Urn, Buffon's Needle, Craps, Monty Hall, and many more. Select an experiment from the drop down menu and click "About" to read its description. Then, set the parameter values. Set the sample size using the "Update" box and the number of samples using the "Stop" box. The single arrow button takes one sample and the double arrow button takes the number of samples selected. Graphs of the theoretical and empirical distributions are shown.

This site offers software tools, instructional materials and online tutorials about college-level probability and statistics. The SOCR tool has interactive graphs and information about dozens of distribution models, as well as a large collection of statistical techniques for online data analysis, visualization, and integration. Students can see how modifying parameters affects the mean, median, variance, and other measures. The site also features more than 50 probability-related experiments, computer-generated games illustrating various statistical concepts, and a collection of data modeling aids. Links to additional resources include online statistics calculators, more graphing and data analysis tools, and other applets about statistics and probability modeling. The site is a useful resource for teachers seeking demonstrations or online experiments for college probability or statistics classes.

This calculator, created by authors Leon Avery and Ivo Dinov of the University of California, Berkeley, determines the level of significance for the Wilcoxon-Mann-Whitney U-statistic. Users can enter N1, N2, and U or simply enter the raw data. This interactive resource requires Java to be enabled for use. If not, the calculator will not load properly. This is a nice reference tool for anyone interested in statistical testing.
