## Simple Percent Agreement

By Dr. Danica Krunic In AllgemeinThis is the main reason why the percentage of concordance should not be used for scientific work (e.g. B doctoral theses or scientific publications). Inter-board reliability is the degree of adequacy between evaluators or judges. If everyone agrees, IRR is 1 (or 100%) and if everyone does not agree, IRR is 0 (0%). There are several methods of calculating the IRR, from the simple (e.g.B. percentage overset) to the most complex (e.g.B Cohen`s Kappa). What you choose depends largely on the type of data you have and the number of evaluators in your model. As you can probably see, calculating percentages can quickly get complicated for more than a handful of reviewers. For example, if you had 6 judges, you would have 16 pair combinations to calculate for each participant (use our combination calculator to find out how many couples you would get for multiple judges).

For example, if you want to calculate the percentage of concordance between the numbers five and three, take five minus three to get the value of two for the counter. In this competition, the judges agreed on 3 points out of 5. The percentage of concordance is 3/5 = 60%. For example, multiply 0.5 by 100 to get a percentage of 50%. The basic measure of reliability among evaluators is a percentage of agreement between evaluators. When calculating the percentage agreement, you need to determine the percentage of the difference between two numbers. This value can be useful if you want to see the difference between two numbers as a percentage.
