The standard deviation of all possible means selected from the population is known as the standard error of the mean. It measures the variation in the means of multiple samples that could be drawn from the same population. It is different from the standard deviation of the population, which measures the variation of the individual data points in the population. The standard error of the mean is used to estimate the precision of the sample mean as an estimate of the population mean.
