Shodor Interactivate: Normal Distribution
Change the standard deviation of an automatically generated normal distribution to create a new histogram. Observe how well the histogram fits the curve, and how areas under the curve correspond to the number of trials.

Khan Academy: Normal Distributions Review
Normal distributions come up time and time again in statistics. A normal distribution has some interesting properties: it has a bell shape, the mean and median are equal, and 68% of the data falls within 1 standard deviation.
Hofstra University
Hofstra University: Review Exercises Random Variables..
Interactive review problems are offered to practice the concepts of random variables and statistics. Topics covered include, Bernoulli trials, normal and binomial distributions, Chebyshev's rule, and the like.
University of Glasgow
Steps Statistics Glossary: Discrete Random Variable
An overview of the term "discrete random variable." The site continues with the definition "continuous random variable" so that the user may compare the two.
University of Glasgow
Steps Statistics Glossary: Expected Value
Site defines statistical expected value as the population mean and discusses it's usefulness as a summary value of a variable's distribution. The formula for calculating expected value is provided, as is an example.
