21)Factors contributing to reliability include all of the following EXCEPT A)the precision and clarity of the operational definition of the construct. B)the care and precision with which we carry out the measures and follow procedures of the operational definition. C)the attention we pay to making sure we have a large number of participants. D)the number of independent observations on which to base the score. 22)Scale attenuation effects result from A)the range of a scale being too wide. B)participant scores bunching at the top end of a scale. C)participant scores bunching at the low end of a scale. D)the restricted range of a scale. 23)Suppose everyone taking this test received 100%. This would exemplify A)a minor miracle at least. B)a reliable test. C)scale attenuation effects. D)a floor effect. 24)Suppose that this exam was so difficult that everyone scored low. In this case, the exam would be showing A)a ceiling effect. B)a floor effect. C)high internal consistency reliability. D)low interrater reliability. 25)Internal consistency reliability is used when scores for participants are based on A)several observations made by several observers. B)several observations. C)different measures over several times by several observers. D)one score only. 26)The use of a measurement scale with a restricted range can result in A)statistical squeeze. B)truncated statistical measures. C)enhanced reliability. D)scale attenuation effects. 27)Scale attenuation effects is a problem that A)cannot generally be reduced in experimental research. B)occurs only when the dependent variable is a measure of a physical property. C)is related to the effective range of a measure. D)can be solved by increasing sample size. 28)A researcher is designing a study on the effects of TV on the IQs of 9-12 year old children. The IQ test he is using was designed to measure IQs in adults. This is an example of a(n) ________ problem. A)internal consistency reliability B)construct validity C)test-retest reliability D)effective range 29)Internal consistency reliability refers to A)the participant’s private versus public attitudes. B)a type of interrater reliability. C)the comparison of one test version with another. D)the extent to which multiple observations that form a single test score are intercorrelated. 30)A ceiling effect occurs when A)participants are very unmotivated during research. B)a measure does not have sufficient range on the high end. C)a measure does not have sufficient range on the low end. D)a measure has too much range on the high end. Â
