When several random samples are extracted from a population, the standard error of the mean is essentially the standard deviation of different sample means from the population mean. However, multiple samples may not always be available to the statistician. Fortunately, the standard error of the mean can be calculated from a single sample itself.

Formula 1: Calculating standard error (SE) for a mean or a mean difference of pre-post groups from 95% confidence interval. Formula 2: Calculating standard 

The standard error of the mean is the standard deviation of the sampling distribution of the mean. In other words it is the standard deviation of a large number of sample means of the same sample size drawn from the same population. The term standard error of the mean is commonly (though imprecisely) shortened to just standard error. The standard error of the mean is the standard deviation of the sample mean estimate of a population mean.
