standard error of measurement

stan·dard er·ror of mea·sure·ment

(SEM) (stan'dărd er'ŏr mezh'ŭr-mĕnt)
A test based on error with regard to reliability. The difference between the obtained test result and the hypothetical true result.

However, absolute test-retest reliability of measurements expressed as either the standard error of measurement (SEM) or minimal detectable change (MDC) and concurrent validity of this device compared with a gold-standard strength assessment tool expressed as Intra-class Correlation Coefficient (ICC) has not been reported in literature.
For the evaluation of test-retest was used the Intraclass Correlation Coefficient (ICC), the intra-examiner method and the standard error of measurement was calculated from the formula: SEM: SD V (1 - ICC), where SD is the standard deviation of mean at baseline; and ICC value was derived from test-retest reliability (15).
The standard error of measurement (SEM) was calculated from the data obtained from the 10 repetitions of shoulder abduction performed by participants, and was calculated using the square root of the error mean square term, obtained from the ANOVA test.
The optional short-term typical or standard error of measurement
Furthermore, we performed the following tests: Kolmogorov-Smirnov test, coefficient of variation (CV), standard error of measurement (SEM), paired- sample T-test, Pearson correlation, coefficient of determination (R2), Cronbach's Alpha, Bland-Altman (Bland & Altman, 1986) and average relative error.
[22] Absolute reliability was examined with the standard error of measurement (SEM).
(92) This trend, along with the vast majority of states already rejecting strict IQ score cutoffs, led the Supreme Court to the conclusion that the societal consensus was that intellectual disability defenses should take into account standard error of measurement and that strict cutoffs like Florida's were neither "proper [nor] humane."

In an article published in the University of Richmond Law Review in 2007, Katherine Gustafson and I reviewed the drafting history and the relevant scientific and professional literature, showing that the statutory language referring to IQ testing was intended to incorporate standard professional practice, including recognition of the standard error of measurement in interpreting IQ scores.
Furthermore, in each subject's stance phase, to check how much error of the knee joint angle appeared at the time when the SD was the largest, the standard error of measurement (SEM) was computed as an index of quantitative reliability [9] using the following formulas:
Intraclass correlation coefficients (ICC) and standard error of measurement (SEM) were calculated for hip, knee, and ankle sagittal plane angular displacements.
Student attains Full Scale IQ score of 115 (one standard deviation above the mean) or higher on the Wechsler Intelligence Scale for Children or IQ score of 116 (one standard deviation above the mean) or higher on the Stanford-Binet Intelligence Scale (with consideration of 1.0 standard error of measurement at the 68% confidence interval).
Instead of evaluating accuracy using procedures recommended by Cone, accuracy within the CBM-R literature typically is referred to in terms of standard error of measurement (SEM).
