"I really love this version of NCSS and as teacher and researcher in a medical field I can say there aren't many things I miss in it... The help system is another strong feature; the transformations interface is one of my favorites as well."

Dr. Adrian Buzea

"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."
