The standard error of a statistic used as an estimator of a population parameter is the standard deviation of the sampling distribution of the statistic. It measures the variability or spread of the sample means or proportions around the population parameter. The standard error depends on the sample size, the variability of the population, and the sampling method. The smaller the standard error, the more precise the estimate is likely to be.
