I adore NCSS and PASS. I have been using them for 20 years now.

Mario Martinez Gonzalez, MPH, FEE, MD, Universidad Nacional Autonoma de Mexico

"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."
