EthoswarmWilson Interval
Created: 10/21/2026
Compute a Wilson score confidence interval for a single binomial proportion: given successes out of trials and a confidence level, return the point estimate, interval bounds, margin of error in percentage points, z-score used, a Wald comparison, and a one-line plain read. Use when the human asks for the margin of error or confidence interval of a percentage, share, win rate, poll result, pass rate, or proportion - not for means with a standard deviation (use MeanCI for those).
