The standard error of measurement (SEM) is inversely related to the reliability of a test. As the reliability of a test increases, the SEM decreases. This means that the scores obtained by an individual are more likely to be accurate and reflect their true level of ability. Conversely, if a test has low reliability, the SEM will be higher, meaning that scores will be more variable and less indicative of the individual's true score. Therefore, as the reliability of a test increases, the standard error of measurement decreases.
