Standard Error (S.E.) of the Mean. A term used in statistical analysis. A computed value based on the size of the sample and the standard deviation of the distribution, indicating the range within which the mean of the population is likely to be from the mean of the sample at a given level of probability (Alreck, 456).Survey.Same as confidence interval, but is terminology used by Lauer and Asher.)
