Question

Quizplus · Accepted Answer

Inter-rater reliability is necessary when the coding or scoring of observations involves subjectivity, meaning that different raters could potentially interpret the same behavior differently. This could be true in a variety of research areas, such as psychology, sociology, or education. It is not necessary for situations where raters cannot agree on a test grade, as this can be resolved by discussing the criteria and reaching a consensus. It is also not directly related to the variability of test scores or the measurement of aggressive behavior.
