Dependable & Accurate

NCSS was created over fifteen years ago by Dr. Jerry Hintze, the renown statistician dedicated to developing powerful yet intuitive statistical analysis software. Since then, the program has integrated the most robust and algorithms available. Each routine has been time-tested and verified against textbooks journal articles. One of the most accurate statistical packages, NCSS calculates with seventeen-digit, double-precision accuracy.

Data Entry/Management

Entering data is simple using our Microsoft Excel® compatible spreadsheet. NCSS can also import and export:

So if your data is in another format, chances are you can easily import it into NCSS 97.

Report Editor

All reports are displayed using our built-in word processor. You can quickly view, edit, save, and print your output. Reports are stored in the rich-text format that can be read by most word processors, so you can easily save NCSS reports for further use in Word®. The output document mixes text and graphs together. The text portions of the reports are formatted using tabs (not spaces), so they are easily reformatted.

Statistical Procedures & Plots
Delivering high-end statistical routines and plots that are found in software costing 2 to 3 times more than NCSS, the program is an affordable solution for in-depth statistical analysis, including ANOVA, Design of Experiments, Curve Fitting, Categorical Data Analysis, and Multivariate Analyses. Thousands of users worldwide depend on NCSS for their mission-critical data analysis, including economists, epidemiologists, psychologists, academic and market researchers, and quality control professionals.
