Interobserver agreement is a measure used in research to assess the consistency or reliability of observations made by different individuals or observers. It refers to the degree to which different observers agree when making judgments or ratings of the same event, behavior, or phenomenon. Interobserver agreement is important in research to ensure the validity and reliability of findings, as well as to determine the consistency of measurements or observations across multiple observers. This measure can be used in various fields such as psychology, sociology, medicine, and education to evaluate the reliability of data collected through observational studies or assessments.
