Web pages that perform statistical calculations
Links to over 300 Web sites performing interactive statistical calculations.
WebStat
Java-based interactive programs providing elementary statistics (summary statistics; 1- and 2-sample Z, T and F tests; chi-squared test and regression) and graphics (histograms, stem/lef plots, boxplots, dotplots, parallel coordinate, means, scatter, quantile-quantile and time series plots). Data entry from keyboard, URL, or local files.
Statistical Calculators
A collection of interactive CGI, Java and Xlisp-Stat services giving probabilities and random deviates for normal, exponential, binomial, Poisson, etc. distributions; linear correlation and regression; t-tests; and more.
Statistical Tools Online
