Exam 12: Evaluating the Methods Sectioninstruments
Reliability is reported as a correlation expressed as the degree of the relationship between two sets of scores. Possible scores in these correlations can range from ______.
D
All the potential effects that alter the true score, such as the limitations of the test, time of day in responding to the measure, and lack of consistent administration procedures, are referred to as ______.
B
Discuss the advantages and disadvantages of using self-report inventories.
Heppner et al. (1992) noted the advantages and disadvantages of self-report and inventories. One of the most important advantages to researchers in using self-report and inventories is the ease and time of administering them. Self-report approaches generally do not require extensive training to administer, and for the most part are brief. A second advantage is that the researcher can assess nonobservable events such as cognitions and feelings that generally cannot be measured through direct observation. Heppner et al. (1992) suggested that the most serious problem with self-report measures is the possibility of distortion or bias by the responder. Respondents may deny or repress feelings or cognitions that are troublesome or incongruent with how they see themselves.
Which type of reliability involves the measurement of the consistency of scores over a period of time?
______ scores are based on a predetermined level of performance to a comparison study.
In ______ approach, scores are interpreted based on the comparison of one group's performance with other groups', all of whom represent a clearly defined population.
Scorer reliability is the most frequently reported type of reliability.
Researchers and practitioners have noted the importance of using measures of the dependent variable that are culturally, gender, and diversity-issue appropriate.
Thorndike and Thorndike-Christ noted that many tests and measures are designed to "reflect the values and experiences of typical ______."
What are the three components of construct validity Urbina (2004) identified?
Strong indicators of reliability in a particular test or measure have a score of at least ______.
Instrumentation is that area of the methods section where the researchers systematically describe the dependent measures used in the study.
Use of an inappropriate test or dependent measure can result in test bias and problems with interpreting outcomes.
Without information on the reliability and validity of the instruments used in a quantitative study, it is difficult to conclude whether the study results obtained are accurate.
Researchers have noted that one of the most important considerations in determining the quality of the dependent measures is the reliability of the instruments and dependent variables. Define and discuss reliability of the instruments and the various forms of determining reliability.
Psychometricians have long acknowledged that validity is the least important characteristic of a test.
A basic type of validity that concerns the extent to which responses on test items represent a particular content is known as ______.
Discuss alternate-form reliability. What is a benefit of using this approach?
______ concerns the consistency of a measure based on content, for instance, when two forms of the measure are administered to a sample and reliability coefficients are obtained between them.
