# SOP: Sample Size Estimation

Determine required sample size or repetition count through power analysis, ensuring the experiment has sufficient statistical power to detect the expected effect.

## Execution

Subagent — spawned via subagent-spawning/spawn-agent skill.

## Why Subagent

Sample size estimation requires multi-step calculations based on effect size, variance estimates, and design type, involving deep statistical reasoning suited for an independent subagent.
