1. Research Tools and Randomizers

Research Randomizer: http://www.randomizer.org

This site has a free set of tools for help in generating random numbers, assigning participants to experimental conditions, and drawing random samples from larger populations of stimuli, participants, or observations.

Random.org: http://www.random.org

This site offers a host of tools for generating, simulating, and testing for random patterns of values, including tools appropriate for random sampling (with and without replacement), randomizing assignment to research conditions, and randomizing orders of presentation for survey questions and research stimuli. This extensive site also includes simulations for games ranging from dice-rolling and coin flipping to Powerball and Keno.

2. Statistics Textbooks

Vassar Stats "Concepts and application of Inferential Statistics": http://vassarstats.net/textbook

This on-line text by Richard Lowry (Vassar College) covers most of the basic and a number of more advanced topics. A strength is that it's linked to a full "package" of free statistical tools called VassarStats (accessed by clicking on the "Online Statistical Computation" hot link on the left of the home page.

HyperStat Online: An Introductory Statistics Textbook: http://davidmlane.com/hyperstat/index.html

This on-line text by David Lane (Rice University) covers most of the basic and a number of more advanced topics. A related pdf version of the text can be downloaded at http://onlinestatbook.com . A strength of the on-line text is the inclusion of hyperlinks to multiple other, more detailed sources and tools. It is part of the larger Rice Virtual Lab in Statistics (RVLS) where one can find instructional simulations and free analysis tools. http://onlinestatbook.comrvls

Statsoft Electronic Statistics Textbook: http://www.statsoft.com/textbook (also available in hard copy as statistics: Methods and Applications)

This on-line text is part of the supporting materials for the major statistical software package called Statistica (by Statsoft).
