How to Change Your NCSS, PASS and/or GESS Serial Numbers

Occasionally, you may need to change your serial number. This may be because you are upgrading to a newer edition of NCSS, PASS, and/or GESS or because you are changing from the trial version to the fully-licensed version. To change your serial number, do the following:
  1. Start NCSS, PASS, and/or GESS and go to the NCSS/GESS spreadsheet or PASS Home Window.
  2. From the Help menu, choose Serial Numbers.
  3. Write down the old serial number in case you need it. Replace the old serial number with the new serial number.
  4. Click OK to close the Serial Numbers window.
  5. Quit NCSS or PASS.
  6. Start NCSS or PASS up again. The program is now using your new serial number. If you have entered an incorrect serial number, you will get a 7-day trial or expiration notice.

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.

I have used several statistics tools, but NCSS is the best statistics tool. It is easy to use because the interface and menu are easy to be used. And NCSS is very useful to support an analysis [in] data research.
