“I’ve used NCSS since 1986 and PASS since 1997. The utility, precision, documentation, output and ease-of-use of your products are the best in the business. Thank you!”

Tim Gohmann, Ph.D.

I am a very satisfied user of NCSS. For years I used SPSS in my consulting work, but the cost got to be exorbitant. When I started using NCSS, I found it easy and intuitive to use and extremely accurate in its results. It is not only my statistical analysis program of choice but I have recommended it to many of my clients as well. When I've had questions and called NCSS, I have always gotten expert help and advice and never had a problem go unsolved. Keep up the good work.
