This is a basic article on the gamma distribution. The article fits the general format of Wolfram MathWorld articles on distributions: the basic properties are given with some derivations.
This is an interactive applet for the gamma distribution requiring the Wolfram CDF player.
A video tutorial on using R to sample from various distributions.
This video lecture introduces the cumulative distribution function and discusses properties of the function.
This video outlines the uses of two-ways tables and the different ways these tables can be analyzed. The video uses "real-world" data and problems to frame the concepts.
