Question

Quizplus · Accepted Answer

Reliability in the psychometric sense refers to the consistency of a measure over time, across different raters, or within a test. It is not an all-or-none measurement, as there can be varying degrees of reliability. A test may be reliable in one context and unreliable in another due to factors such as differences in the sample or test administration. A reliability coefficient may be derived for personality tests, but it may be more difficult to establish due to the subjective nature of personality traits. Alternate forms reliability may also be derived for personality tests.
