Power & Sample Size

Power & Sample Size is included with E-PICOS All Access. It supports a-priori sample-size planning and achieved-power calculations with guided pathways.

Start from a research goal, an outcome structure, or a known statistical test. The module helps document assumptions such as effect size, alpha, target power, allocation, and design parameters.

The current workspace covers 20+ test pathways and includes power curves, sensitivity analysis, effect-size guidance, and report-ready outputs. See the calculator pages in this section for supported methods and inputs.
