The basic measure for Inter-Rater`s reliability is a percentage agreement between advisors. Step 5: Look for the average value for political groups in the Accord column. Average – (3/3 – 0/3 – 3/3 – 1/3 – 1/3) / 5 – 0.53 or 53%. Inter-Rater`s reliability for this example is 54%. When calculating the percentage agreement, you must determine the percentage of the difference between two digits. This value can be useful if you want to show the difference between two percentage numbers. Scientists can use the two-digit percentage agreement to show the percentage of the relationship between the different results. When calculating the percentage difference, you have to take the difference in values, divide it by the average of the two values, and then multiply that number of times 100. Multiply the quotient value by 100 to get the percentage parity for the equation. You can also move the decimal place to the right two places, which offers the same value as multiplying by 100. As you can probably tell, calculating percentage agreements for more than a handful of advisors can quickly become tedious. For example, if you had 6 judges, you would have 16 pairs of pairs to calculate for each participant (use our combination calculator to find out how many pairs you would get for multiple judges). Step 3: For each pair, put a “1” for the chord and “0” for the chord.

For example, participant 4, Judge 1/Judge 2 disagrees (0), Judge 1/Judge 3 disagrees (0) and Judge 2 /Judge 3 agreed (1). The reliability of the interrater is the level of correspondence between councillors or judges. If everyone agrees, IRR is 1 (or 100%) and if not everyone agrees, IRR is 0 (0%). There are several methods of calculating IRR, from the simple (z.B. percent) to the most complex (z.B. Cohens Kappa). What you choose depends largely on the type of data you have and the number of advisors in your model. If you have multiple advisors, calculate the percentage agreement as follows: A major error in this type of inter-rater trust is that it ignores the random agreement and overestimates the level of the agreement. This is the main reason why the percentage of consent should not be used for scientific work (i.e. doctoral theses or scientific publications). The field in which you work determines the acceptable level of agreement.
