What is ICC?
The Intraclass Correlation Coefficient (ICC) measures the reliability of ratings or measurements made on the same set of subjects. It reflects both the degree of correlation and agreement between measurements. Unlike Pearson correlation, ICC accounts for systematic differences between raters or methods.
