About Us

NCSS, LLC

NCSS was founded in 1981 to supply statistical software to the research community. Since then, tens of thousands of customers have used NCSS software (NCSS and PASS) for statistical, graphics, and power analysis / sample size purposes. The company is led by Dr. Jerry Hintze, an experienced Ph.D. statistician.

Our Mission

For the last 40 years, our mission has been to provide accurate, user-friendly, fully-supported statistical analysis, graphics, and sample size tools. We seek to produce applications the research community requests, as well as new tools to guide improvement in analysis and sample size estimation.

"PASS is a great program. It does so much and is easy to use. It’s much better than the other sample size programs I’ve used—it has helped me greatly in my research."

Ken Lawson, Ph.D., The University of Texas

"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
