About the Product

The NCSS Software Bundle combines two of the most powerful and intuitive statistical tools on the market: NCSS 2025 and PASS 2025. This professional-grade suite is the global standard for researchers in the medical, pharmaceutical, and social science sectors who need to acquire precise data insights.

NCSS 2025 provides hundreds of statistical and graphics tools to analyze and visualize data, while PASS 2025 is the world-leading software for power analysis and sample size estimation. By purchasing this bundle, you obtain a seamless workflow—from planning the size of your clinical trial to performing the final complex regression and meta-analysis—all without ever needing to write a single line of code.

The Problem It Solves

Researchers often struggle with underpowered studies that fail to reach significance or overpowered studies that waste valuable resources. The NCSS Bundle solves this by allowing you to get the exact sample size needed through PASS 2025, which covers over 1,200 statistical scenarios. Once your data is collected, NCSS 2025 eliminates the "fear of statistics" by offering a user-friendly, point-and-click interface to unlock advanced mixed models, survival analysis, and publication-ready graphics that would otherwise require intensive R or SAS programming.
