| standard error of the mean |
A measure of variability. The standard error of the mean quantifies how accurately the true population mean is known. A measure of the variability of the mean of the sample as an estimate of the true value of the population mean. The larger the sample size the smaller the standard error of the mean. Used in computing confidence intervals. In a clinical trial, the larger the sample size the tighter the 95% CI is around the point estimate of the study.
