This Kappa Represents What Level Of Agreement
Originally, agreements between judges were binary in nature, that is, they either totally agreed or disagreed at all. In the case of red tones, we cannot have a binary match. Take, for example, these two scenarios. There are actually two categories of reliability when it comes to data collectors: reliability beyond multiple data collectors, which is the reliability of interraters, and the reliability of a single data collector, called intrarater reliability. For a single data collector, the question is: will an individual, in the same situation and phenomenon, interpret the data in the same way and record exactly the same value for the variable each time this data is collected? Intuitively, it might seem like a person behaving in the same way in relation to the same phenomenon every time the data collector observes this phenomenon. However, research shows the error of this hypothesis. A recent study on intrarater reliability in the evaluation of bone density X-rays found reliability coefficients of only 0.15 and 0.90 (4). It is clear that researchers are right to carefully consider the reliability of data collection as part of their concern for specific research results. We find that in the second case, it shows a greater similarity between A and B than in the first. This is because, although the percentage of concordance is the same, the percentage of concordance that would occur “by chance” is significantly higher in the first case (0.54 versus 0.46). Cohens Kappa is a unique synthesis index that describes the strength of the Inter-Rater agreement. Mainly due to logistical, political, and economic issues, test designers often have to accept an assurance estimate based on test management. Squared-Error Loss approaches use the square distance between a person`s score and the cutoff score to determine reliability.
