SKILL.md

Calculate statistical power and determine required sample sizes for research studies. Essential for experimental design, grant writing, and meeting NIH rigor and reproducibility standards.

Statistical Power Definition: Probability of detecting a true effect when it exists (1 - β)

Standard: Power ≥ 0.80 (80%) is typically required for NIH grants and pre-registration

Calculate statistical power and required sample sizes for research studies. Use when: (1) Designing experiments to determine sample size, (2) Justifying sample size for grant proposals or protocols, (3) Evaluating adequacy of existing studies, (4) Meeting NIH rigor standards for pre-registration, (5) Conducting retrospective power analysis to interpret null results.
