Free Statistical and Research Tools

I have come across a wiki and a web site with free resources to use in research, especially quantitative and survey research.

The Impoverished Social Scientist’s Guide to Free Statistical Software and Resources http://maltman.hmdc.harvard.edu/socsci.shtml

Digital Research Tools (actually has other resources – some not free – for the entire research process – bibliography management, writing, etc.) http://digitalresearchtools.pbwiki.com/
