Statistical Software for Study Design to Study Results

For over 30 years, we have worked with academic researchers across many fields to produce publication-worthy sample size, data analysis, and graphics solutions.

Each tool is easy-to-use, well-documented, and carefully validated against published results.

Hundreds of articles are published each year using PASS to estimate the sample size or evaluate the study power, or using NCSS to analyze and visualize the study results.

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.
