standard error
standard errorn. A generalized notion of standard deviation, used to characterize the dispersion of a statistic (such as the sample mean) calculated from randomly sampled data.standard error n (Statistics) statistics the estimated standard deviation of a parameter, the value of which is not known exactly standard error
standard error[′stan·dərd ′er·ər] (statistics) A measure of the variability any statistical constant would be expected to show in taking repeated random samples of a given size from the same universe of observations. standard error see MEASURES OF DISPERSION.standard error
standard error Abbreviation: S.E.
A measure of variability that could be expected of a statistical constant following the taking of random samples of a given size in a particular set of observations. An important standard error is that of the difference between the means of two samples. See also: error Fig. 288 Standard error . standard error an estimate of the STANDARD DEVIATION of the means of many samples, calculated as the standard deviation (s) divided by the square root of the number of individuals in a sample (n), i.e. s /Vn . See Fig. 288 . The SE can be used to assess any SIGNIFICANCE in the deviation of the mean of a sample from the true mean of the whole population.LegalSeeStandardStandard error
Standard errorIn statistics, a measure of the possible error in an estimate. Plus or minus 2 standard errors usually provides a 95% confidence interval.Standard ErrorAn estimate of the standard deviation of a data set. See also: Confidence interval.See STDERR
