 When a measurement of a psychological variable is consistent or stable, it is __________. A)valid B)reliable C)reactive D)both a and c reliable Mary weighed herself and the scale reading was 120 pounds. A few minutes later she weighed herself again and the same scale showed she weighed 125 pounds. The scale is __________. A)reactive B)predictive C)unreliable D)invalid unreliable One way to assess the stability of measures is by computing a Pearson __________. A)coefficient criterion B)linear coefficient C)correlation coefficient D)coefficient of determination correlation coefficient A correlation of 0.00 means that the two variables are __________. A)not related at all B)strongly related C)negatively related D)positively related not related at all Which of the following indicates the strongest correlation? A)+0.48 B)–0.98 C)+0.55 D)–0.02 –0.98 When you read about reliability in an article, the correlation between two test scores will usually be referred to as the __________ coefficient. A)score B)internal C)reliability D)significance reliability A group of students took a cognitive development test on Monday and then took the same test again the following week. Most likely, researchers were assessing the __________ reliability of the measure A)test-retest B)split-half C)odd-even D)inter-item test-retest Which of the following statements about test-retest reliability is FALSE? A)The reliability coefficient of a measure should be at least .80 before the measure is accepted as reliable. B)Sometimes test-retest reliability is artificially high because people remember how they answered the first time. C)Test-retest reliability is the best form of reliability measurement. D)Test-retest reliability is very useful if the variable being measured is expected to stay constant over time. Test-retest reliability is the best form of reliability measurement. Which of the following is an indicator of the internal consistency reliability of a measure? A)split-half reliability B)Cronbach's alpha C)inter-rater reliability D)both a and b both a and b When two raters observe the same behaviors, the extent to which their observations are in agreement is called __________. A)split-half reliability B)Chronbach's alpha C)item-total correlations D)inter-rater reliability inter-rater reliability __________ validity refers to the adequacy of the operational definition of variables. A)Operational B)Construct C)Measurement D)Reliable construct Dr. L reviewed a measurement scale designed to measure extroversion and said that it appeared to measure extroversion. The measure has __________ validity. A)face B)internal C)convergent D)predictive face __________ validity is demonstrated when a measure is NOT related to variables with which it should not be related. A)Convergent B)Concurrent C)Differentiation D)Discriminant Discriminant If participants change their behavior because they know their behavior is being measured, the measure is said to be __________. A)systematic B)reactive C)predictive D)conducive reactive A reliable measure yields consistent results. A)True B)False True Split-half reliability is the correlation of each item on a test with every other item. A)True B)False False The test-retest reliability for intelligence should be very high. A)True B)False true Cronbach's alpha yields a value that represents the average of a number of correlation coefficients. A)True B)False True A commonly used indicator of inter-rater reliability is called Cohen's Kappa. A)True B)False True Predictive validity is a type of face validity. A)True B)False False The Sensation Seeking Scale is an excellent illustration of construct validity. A)True B)False True In a nominal scale, numeric properties are literal. A)True B)False False A 20-item measure of depression would be classified as a ratio scale. A)True B)False false Ratio scales have an absolute zero point A)True B)False true Authorreads2much ID104226 Card SetChapter 5: Measurement Concepts DescriptionChapter 5 Updated2011-09-25T20:39:18Z Show Answers
