Question

Quizplus · Accepted Answer

Interrater reliability is measured using the Intraclass Correlation Coefficient (ICC) and is an important aspect of assessing the consistency and agreement between two or more raters or observers. Therefore, option A is the correct choice. Options B and C are incorrect as interrater reliability should be calculated regardless of the number of raters or whether they are well trained. Option D is also incorrect as interrater reliability only assesses the consistency and agreement between raters or observers, not the validity of their observations.
