What is an example of inter-rater reliability?
Interrater reliability is the most easily understood form of reliability, because everybody has encountered it. For example, watching any sport using judges, such as Olympics ice skating or a dog show, relies upon human observers maintaining a great degree of consistency between observers.
What is inter-rater reliability in research methodology?
Interrater reliability (also called interobserver reliability) measures the degree of agreement between different people observing or assessing the same thing. You use it when data is collected by researchers assigning ratings, scores or categories to one or more variables.
How do you establish inter-rater reliability?
Two tests are frequently used to establish interrater reliability: percentage of agreement and the kappa statistic. To calculate the percentage of agreement, add the number of times the abstractors agree on the same data item, then divide that sum by the total number of data items.
What is a good inter-rater reliability?
Inter-rater reliability was deemed “acceptable” if the IRR score was ≥75%, following a rule of thumb for acceptable reliability [19]. IRR scores between 50% and < 75% were considered to be moderately acceptable and those < 50% were considered to be unacceptable in this analysis.
