Standard Error Of Measurement In Assessment
Dec 27 2023 nbsp 0183 32 The Standard Error of Measurement SEM is a statistic that helps us understand the accuracy of a test score It represents the amount of error or variability that can occur when measuring a student s true ability Standard Error of Measurement is directly related to a test’s reliability: The larger the SEm, the lower the test’s reliability. If test reliability = 0, the SEM will equal the standard deviation of the observed test scores. If test reliability = 1.00, the SEM is zero.
