The standard error is a measure of the variability of sample estimates of a population parameter. It tells us how much the sample statistics (such as the mean) vary from sample to sample, and therefore how reliable our estimates of the population parameter are. It is calculated as the standard deviation of the sampling distribution of the statistic.
