WebbFor a binomial problem, the standard deviation of a count is n p ( 1 − p). Conversely, the standard deviation of the sample proportion decreases with increasing n and is p ( 1 − p) n. I can do the division by n but I don't have a feel why standard deviations move in opposite directions. binomial-distribution standard-deviation Share Cite WebbStandard deviation is the sqrt of the variance of a distribution; standard error is the standard deviation of the estimated mean of a sample from that distribution, i.e., the spread of the means you would observe if you did that sample infinitely many times.

WebbThe normal approximation to the binomial distribution tends to perform poorly when estimating the probability of a small range of counts, even when the conditions are met. … WebbThe binomial confidence interval is a measure of uncertainty for a proportion in a statistical population. It takes a proportion from a sample and adjusts for sampling error. Let’s say you needed a 100 (1-α) confidence interval (where α is the significance level) on a certain parameter p for a binomial distribution.

WebbIt is the standard deviation of the expected error. 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.
