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 34 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.

"Your [PASS] routines are flexible and easy to use and your customer service and support is A-double-plus."
