Question

Quizplus · Accepted Answer

The precision of measurement index in item response theory reflects how consistently an instrument measures a construct across different items within the test, which is a form of internal consistency reliability. This type of reliability assesses the consistency of results across items within a test, rather than across different administrations (test-retest), different scorers (inter-scorer), or different forms of the test (alternate form).
