"I have been using NCSS for almost 20 years. I absolutely love it. It does everything [I need that] SPSS or SAS does, is more reasonably priced and user friendly and has wonderful customer support. If you have a problem, when you call a real person (who created the software) gently talks you through it. It is a great product and a great company."
"Two reasons for choosing your product [PASS]: all-around methods and options + very good documentation."
