Document Summary

Objective assessment: measurement that is not dependent on the individual making the assessment. Subjective assessment: measurement that relies on interpretation by the individual making the measurement. Reliability: the consistency of scores that are expected to be the same across time. Error variance: variations of a measurement that are the result of irrelevant, chance fluctuations. Internal consistency reliability: degree of consistency between subparts or equivalent parts of a test. Reliability determined in two ways: having the same measures (or slight variations of such) yielding the same results (internal consistency reliability measured with. Test-retest reliability: the degree of consistency between the results of the same test taken on different occasions. Validity: the extent to which a test measures what it is supposed to be measuring. Construct validity: the extent to which a test truly measures a theoretical construct. Convergent validation: the extent to which an assessment is related to what it should be related to.
