ABOUT THIS SITE



Research Randomizer is a free service offered by Social Psychology Network for researchers, students, and others interested in generating sets of random numbers. See below for some random information about the site.


WHAT ARE THE SYSTEM REQUIREMENTS NEEDED TO RUN RESEARCH RANDOMIZER?

All that Research Randomizer requires is a standard web browser connected to the Internet (e.g., Chrome, Safari, Firefox, Internet Explorer) — no specialized software, plugins, or extensions.


HOW DOES RESEARCH RANDOMIZER GENERATE ITS NUMBERS?

As with most computer-based "random number generators," this program is best described as a "pseudo-random number generator" because the numbers are generated by use of a complex algorithm (seeded by the computer's clock) that gives the appearance of randomness. For most purposes this should be adequate. If, however, the demands of your experiment require "true" random numbers, or if you're interested in learning more about them, we suggest you visit HotBits. The output from HotBits is not as customizable as the output from Research Randomizer, but the numbers are generated by radioactive decay rather than a computer algorithm.


WHO DESIGNED RESEARCH RANDOMIZER?

The original idea and programming for Research Randomizer came from Geoffrey C. Urbaniak in 1997. Research Randomizer was then jointly developed with Scott Plous, Executive Director of Social Psychology Network, and online tutorials were added to the main program. In 2007, Scott Plous and web developer Mike Lestik redesigned the site and added new content, and in 2015 the site was further updated by Scott Plous and Jeff Breil, a professional designer based in Lancaster, Pennsylvania.


HAS RESEARCH RANDOMIZER RECEIVED ANY HONORS?

Yes, Research Randomizer has received a number of honors,
