Interrater reliability refers to the degree of agreement or consistency between different coders or assessors when they measure or evaluate the same phenomenon. This measurement is crucial in ensuring that a given data set is interpreted consistently across different individuals, which enhances the credibility and reliability of the data collected.

By focusing on a coder's agreement with peer records, this concept highlights how multiple professionals can evaluate the same data sources and arrive at similar conclusions or classifications. High interrater reliability indicates that different coders can replicate findings effectively, thereby validating the accuracy and consistency of the data analysis process.

In contrast, measuring consistency of records by a single coder pertains to intrarater reliability, while validation of data by different researchers and the accuracy of a unit of measurement touch upon other aspects of reliability and validity in research but do not specifically address the agreement between raters.
