About nQuery

nQuery is a statistical software platform designed to help researchers and biostatisticians calculate sample sizes and power for clinical trials, medical studies, and other research projects.

The software supports a wide variety of trial types and analysis methods, making it a core tool in planning statistically sound research that meets regulatory and scientific standards.

With support for two-arm tests, multiple comparisons, repeated measures, and adaptive designs, nQuery assists teams in navigating complex statistical requirements across phases of research. Its interface is tailored to balance depth of capability with usability so statisticians, data analysts, and clinical research professionals can perform robust calculations efficiently.
