Chi-square calculator (John Walker)
This JavaScript application may be used to compute critical values and p-values for the chi-squared distribution.

StaTable statistical calculator (Cytel Statistical Software)
This java applet provides critical values and significance levels for a variety of discrete and continuous distribution functions.

F-table calculator (David M. Lane)
To use this JavaScript F-table calculator, enter the degrees of freedom for the numerator and the denominator and the estimated F-statistic. The calculator computes the associated p-value.

Probability Calculator (Javier R. Movellan)
This page provides critical values and p-values for the normal, F, t, Chi-square, binomial and uniform distributions.

Probability Distribution Functions (JavaStat)
The JavaScript application on this page computes either critical values or p-values for the normal, t, F, or Chi-squared distribution functions.

Scientific Calculator (John C. Pezzullo)
A JavaScript calculator that computes critical values and p-values for normal, t, F, and Chi-squared distributions.

This Java applet can be used to compute critical values and p-values for the binomial, poisson, normal, t, chi-squared, and F distributions.

Statlet: Calculate and plot probability distributions
This page provides a Java applet that calculates significance levels and p-values and plots the PDF and CDF for 24 different density functions. (It also plots the survivor, log survivor and hazard functions corresponding to these density functions, but that's a topic for another course....)

Z table (David M. Lane - HyperStat Online)
This graphical Java applet can be used to compute and display either critical values or p-values for a normal density function.
