Which is not a form of reliability?
Options:
(a) Test-retest reliability
(b) Equivalent-forms reliability
(c) Split-half reliability
(d) Content-base reliability
✅ Correct Answer:
(d) Content-base reliability
Explanation:
Reliability refers to the consistency of a test or measurement instrument. Common forms of reliability include:
Test-retest reliability: Consistency over time.
Equivalent-forms reliability: Consistency between two forms of a test.
Split-half reliability: Consistency between halves of a test.
Content-base reliability is not a recognized form of reliability; rather, content validity assesses whether a test covers the intended content adequately. Understanding reliability and validity is crucial in educational measurement, test development, and assessment practices, which are frequently tested in PPSC exams.
