1.Methods of studying, defining, and estimating the consistency or inconsistency of test                           scores deal with the ______ of test scores. a)validity b)appropriateness c) reliability d)stability 2.Given that mechanical aptitude is a stable characteristic, scores of a given person on a mechanical aptitude test taken at different periods of time should a) be similar b)be different c)be exactly the same d)change due to experience 3.Consistency in test scores is important because a)consistency means a test is measuring what it is designed to measure b)inconsistent tests must be given many times c)inconsistent scores don’t provide a good measure of stable traits or attributes d)ability should not change over time 4.Thorndike (1949) would place “motivation” under which one of the following              possible sources of variability in test scores? a)lasting and general characteristics of the individual b) lasting but specific characteristics of the individual c)temporary but general characteristics of the individual d)temporary and specific characteristics of the individual 5.If a student generally does poorly on math exams, but does extremely well on a math              test because the student studied only those things on the exam, we could attribute the                           source of variability in test scores to a)temporary and specific characteristics of the individual b)lasting but specific characteristics of the individual c) variance not otherwise accounted for (luck) d)any of the above 6.Almost all theories of reliability assume that a)people do not differ in levels of a given characteristic b)test scores change over time c)test scores do not change over time d) test scores are influenced by consistency and inconsistency 7.Given the equation X = T + e, X represents ________, T represents ________, and e              represents _________. a)true score; score on the test; error b)true score; error; score on the test c)score on the test; error; true score d)score on the test; true score; error 8.”True score” on a measure of anxiety represents a)a person’s real level of anxiety b) a person’s obtained level of anxiety c)a combination of all factors leading to consistency in anxiety scores d)both a and c 9.The central assumption of reliability theory is that a)measurement errors are essentially random b) measurement errors are not random c)measurement errors are due to deficiencies in the test d)measurement errors cannot be minimized 10.True scores and errors are assumed to be a)highly correlated b)not highly correlated c)uncorrelated d)negatively correlated 1
