Hi all
If you can't afford expensive software like SPSS or SAS, there are free alternatives. I just want to mention a few.
First, there are a couple that are developed by individuals:
MicrOsiris http://www.microsiris.com/
and
Openstat http://www.statprograms4u.com/
Both of these do a really wide variety of statistical procedures and are updated fairly often, and the authors are pretty responsive to your questions. They are also pretty easy to use.
If you want packages developed by organizations, there are also several alternatives.
R: The Comprehensive R Archive Network http://cran.r-project.org/
and
PSPP http://www.gnu.org/software/pspp/
Both of these have communities of users. I recently found an error in PSPP, and the community was very responsive and fixed it pretty quickly. PSPP is also pretty easy to learn and use and has a fair number of statistical procedures. On the other hand R is very difficult to learn, but is probably the most powerful of all programs. But R does have a bunch of GUI or menu driven systems, which are supposed to make operating it easier.
I reviewed the output of a number of programs (excluding R, I haven't had time to learn it yet) and basically they all give the same answers, so they all seem to work well. You can check out my review here as well as links to other programs and other pages that list free stat software.

I hope you find this useful.
