This expression should be valid for all binomial distributions. In practice, if the probability is quite close to one or to zero while you have few samples, the value given by the expression might have large error. Make sure your sample sizes are large enough. – EngrStudent Jun 29, 2015 at 17:59 shoetease

This approximation is based on the central limit theorem and is unreliable when the sample size is small or the success probability is close to 0 or 1. shoet boots with blue zipper

WebbStandard error from data Unfortunately, the standard error of p ^ involves π, and this is unknown in practical problems. To get a numerical value for the standard error, we must … When n is known, the parameter p can be estimated using the proportion of successes: This estimator is found using maximum likelihood estimator and also the method of moments. This estimator is unbiased and uniformly with minimum variance, proven using Lehmann–Scheffé theorem, since it is based on a minimal sufficient and complete statistic (i.e.: x). It is also consistent both in probability and in MSE.
