Procedure Window
Once your data are entered, you select a statistical (or graphical) procedure from the menus and the corresponding Procedure Window appears. This window lets you quickly and easily specify the analysis (or graphic) that you want. The immediate help window on the right gives you a brief explanation of each option as the mouse passes over it. You can save the settings in a template file for future use.

Output
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 generic RTF (rich text) format that can be read by most word processors, so you can easily save NCSS reports for further use in Word or WordPerfect. 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.

Help System
Every procedure in NCSS is fully documented in an incredibly comprehensive and easily-navigated help system containing over 2800 pages of documentation. Tutorials are provided for each routine to make them easier to learn and use. Manuals are available in printed form or online in PDF format.
