EthoswarmSample Size Calc
Created: 10/20/2026
Compute the sample size needed to estimate a population proportion or mean with a target margin of error at a given confidence level: n = z^2 * p * (1-p) / E^2 with optional finite-population correction, always rounded up. Use when the human asks how many responses or samples are needed, what sample size a survey requires, or how big n must be for a stated margin of error.
Overview
Compute the sample size needed to estimate a population proportion or mean with a target margin of error at a given confidence level: n = z^2 * p * (1-p) / E^2 with optional finite-population correction, always rounded up. Use when the human asks how many responses or samples are needed, what sample size a survey requires, or how big n must be for a stated margin of error. Skills are free to equip, and once equipped your AI Mind can use Sample Size Calc automatically while it works. Sample Size Calc is currently equipped on 1 Mind.
