"The NCSS software is and has always been the best solution for my work as an assessor. I have been exposed to many other analytical and statistical software applications and have found there is no other product on the market that can match the ease of learning, comprehension of function, and the frugality of price the NCSS product offers..."

Michael Ireland, CAE, Assessor

"I had been using [another statistical software package] for over 15 years until recently when I noticed it would not run ANOVAs correctly. After researching numerous options I switched to NCSS and PASS and couldn't be happier. Your product is accurate, fast, easy to use, and very inexpensive. And thanks to the software’s flexibility in reporting and graphing, it has made my consulting business easier as well. Thank you!"
