Interactive statistical tools on the Web

SticiGui
 Statistical Tools for Iinternet and Classroom Instruction with a Graphical
User Interface, suite of interactive Java applets developed by P. Stark
at UC Berkeley.

Web pages that perform statistical calculations
 Links to over 300 Web sites performing interactive statistical calculations.

WebStat
 Javabased interactive programs providing elementary statistics
(summary statistics; 1 and 2sample Z, T and F tests; chisquared test and
regression) and graphics (histograms, stem/lef plots, boxplots, dotplots,
parallel coordinate, means, scatter, quantilequantile and time series plots).
Data entry from keyboard, URL, or local files.

Statistical Calculators

A collection of interactive CGI, Java and XlispStat services giving
probabilities and random deviates for normal, exponential, binomial, Poisson, etc.
distributions; linear correlation and regression; ttests; and more.

Statistical Tools Online
