Answer #1

ANSWER: a. Personality

It would be most appropriate to use a 1-year test-retest reliability coefficient for a test of Personality

EXPLANATION: The 1-year test-retest reliability coefficient gives the unbiased results over a consistent period of time. Hence, it is used to test the reliability and stability of the personality which is checked by administering the same test measure at different times. The changes in mood, fatigue, or the stress level is not consistent. it changes with the change of source. Hence, this test cannot be used to measure the reliability of any of these three parameters.
