NCSS 2004 and NCSS 2001 Updates

Existing customers owning a license to NCSS 2004 or NCSS 2001 may download and install this file to update to the latest release of the software. This update will install NCSS 2004, but your NCSS 2001 serial number will continue to work. Some new procedures were added in 2004, but with an NCSS 2001 serial number, you will still only be able to use the procedures that were available in NCSS 2001. For upgrade information click here. In this version, NCSS 2004 and PASS 2005 are combined into one physical program.

"Two reasons for choosing your product [PASS]: all-around methods and options + very good documentation."

I have been using NCSS in my high school class room for 22 years. I find it very easy to use and my students use it to calculate their results for their lab reports, science fair projects, and now they are using it for AP Research projects. It can be used for everything from the basics to the most advanced statistics. NCSS is very affordable for any high school budget.
