What is inter-rater agreement?
A measure of how much two or more raters agree on their assessments or ratings
inter-rater agreement explained in plain English
Inter-rater agreement is a statistical method used to evaluate the consistency of ratings or assessments made by different people, often used in research and evaluation studies to ensure that results are reliable and consistent
Analogy
Imagine two movie critics watching the same film and giving it a rating out of 10 - if they both give it a similar rating, there is high inter-rater agreement, but if one gives it a 5 and the other a 9, there is low inter-rater agreement
Example
A hospital might use inter-rater agreement to evaluate the consistency of diagnoses made by different doctors, to ensure that patients are receiving accurate and reliable care
