Final answer:
Option c is the correct answer. Using more than one set of norms from the publisher is important for both personality tests and aptitude/ability tests to ensure accurate assessments across cultures and diverse populations.
Step-by-step explanation:
Consideration of Norms in Personality and Ability Testing
When administering personality or aptitude/ability tests, it is important to consider the applicability of the norms provided by the test publisher. In the context of personality assessments, such as self-report inventories and projective tests like the Minnesota Multiphasic Personality Inventory (MMPI), different cultural norms could greatly affect the interpretation of test results. This is due to the significant influence of cultural factors on personality traits, and the adaptation of tests across varied cultures may require different sets of norms to ensure accurate and relevant outcomes.
Similarly, for aptitude/ability tests like IQ tests or specific skill assessments, utilizing multiple norm sets can be important, especially when these tests are employed internationally or across diverse populations within a single country. Different educational backgrounds, cultural experiences, and environmental factors could impact the performance on these tests, making it necessary to interpret scores relative to the appropriate norm group.
Therefore, the consideration of using more than one set of norms from the publisher is important for both personality and ability tests (C). This ensures a fair and accurate assessment of the individuals being tested, particularly when the tests are used for important decisions such as employment selection.
