"We have used your product for almost 20 years... It has been a vital part of the research initiatives we have conducted over the years. Through each version of NCSS, we have been able to count on its user-friendly design, broad range of statistical tools and a high level of very personalized customer support..."

I have been using NCSS in my high school class room for 22 years. I find it very easy to use and my students use it to calculate their results for their lab reports, science fair projects, and now they are using it for AP Research projects. It can be used for everything from the basics to the most advanced statistics. NCSS is very affordable for any high school budget.
