NCSS 2007 - Statistical Analysis and Graphics
NCSS includes over 227 statistical procedures and plots. NCSS imports and exports all major spreadsheet, database, and statistical file formats. NCSS easily produces sharp, flexible graphics. NCSS output is easily transferred to popular word processors and presentation software such as PowerPoint.
PASS 2008 - POWER ANALYSIS AND SAMPLE SIZE
PASS Beats the Competition!
PASS performs power analysis and calculates sample sizes. Use it before you begin a study to calculate an appropriate sample size (it meets the requirements of government agencies that demand technical justification of the sample size you have used). Use it after a study to determine if your sample size was large enough.
PASS lets you solve for power, sample size, effect size, and alpha level. It automatically displays charts and graphs along with numeric tables and text summaries in a portable format that is cut and paste compatible with all word processors so you can easily include the results in your proposal.
PASS is a standalone system. Although it is integrated with NCSS, you do not have to own NCSS to run it. You can use it with any statistical software you want.

Array Quality and Filtering
Graphical and numeric summaries, designed to quickly alert the user to artifacts, bad spots, spatial anomalies, or poor arrays, are easily obtained for each array. Expression values may be filtered according to well-described criteria. Several normalization procedures are also on hand.
A wide variety of statistical analyses is available. Each technique is well-documented and described in easy-to-understand terms. Graphical summaries of statistical output help interpret the results. Follow-up statistical analyses are obtained with over 150 statistical procedures in NCSS.
