It is most commonly used by biostatisticians to calculate sample size and statistical power for adaptive clinical trial design.

This software quickly became widely used to estimate the sample size requirements for pharmaceutical trials.

[3] nQuery allows researchers to apply both frequentist and Bayesian statistics to calculate the appropriate sample size for their study.
