The term error of measurement deals with the gap between the desired measurement of the quantity (true score) and the measurement using an operationalized instrument (measured score). The question focuses on the gap or the inconsistency between the two scores. The inconsistency between the two scores can be caused by one of two elements: (a) random or (b) systematic measurement. In the case of a random error, an error has taken place but the direction of the error is unknown and unpredictable. A systematic error is an error that impacts the measurement in an identifiable and systematic manner. This entry examines the impact of both random and systemic errors of measurement, specifically in the context of statistical analyses.
