Margin of error calculator sample mean
WebMar 2, 2024 · If you are estimating a binomial proportion near to p ≈ 1 / 2 based on a sample of size n, then a 95% CI is of the form p ^ ± 1.96 p ^ ( 1 − p ^) / n. for which the margin of error is M = 1.96 p ^ ( 1 − p ^) / n ≈ 1.96 ( 1 / 2) ( 1 / 2) / n = 1.96 1 / 4 n ≈ 1 / n. So, if M = 0.05 = 5 %. then n ≈ 1 / M 2 = 1 / ( .05) 2 = 400.
