The standard error of the estimate is the other standard error statistic most commonly used by researchers. The term standard error of the mean is commonly (though imprecisely) shortened to just standard error. The standard error represents how well the sample mean approximates the population mean. The standard error (se) of a statistic (usually an estimate of a parameter) is the standard deviation of its sampling distribution or an estimate of that standard deviation. With a sample size of 20, each estimate of the standard people almost always say standard error of the mean to avoid confusion with the standard deviation of observations.
