Pearson`s «R-Displaystyle,» Kendall format or Spearman`s «Displaystyle» can measure the pair correlation between advisors using an orderly scale. Pearson believes that the scale of evaluation is continuous; Kendall and Spearman`s statistics only assume it`s ordinal. If more than two clicks are observed, an average match level for the group can be calculated as the average value of the R-Displaystyle r values, or «Displaystyle» of any pair of debtors. The reliability of the interrater is the extent to which two or more advisors (or observers, coders, examiners) agree. It addresses the question of the coherence of setting up a rating system. The reliability of Interraters can be assessed using a series of different statistics. The most common statistics include: percentage agreement, Kappa, product-moment correlation and intraclassal correlation coefficient. High levels of reliability between boards refer to a high degree of correspondence between two auditors. Low levels of reliability among Board members refer to a low degree of agreement between two reviewers. Examples of reliable neuropsychology intershorters are (a) the assessment of the consistency of the physician`s neuropsychological diagnoses, (b) the evaluation of evaluation parameters for drawing tasks such as the Rey Complex Figure Test or the Visual Reproduction Subtest and (c) the… For ordination data, where there are more than two categories, it is useful to know whether the evaluations of the various counsellors end slightly or vary by a significant amount. For example, microbiologists can assess bacterial growth on cultured plaques such as: none, occasional, moderate or confluence. In this case, the assessment of a plate given by two critics as «occasional» or «moderate» would mean a lower degree of disparity than the absence of «growth» or «confluence.» Kappa`s weighted statistic takes this difference into account.
It therefore gives a higher value if the evaluators` responses correspond more closely with the maximum scores for perfect match; Conversely, a larger difference in two credit ratings offers a value lower than the weighted kappa. The techniques of assigning weighting to the difference between categories (linear, square) may vary. Think of two ophthalmologists who measure the pressure of the ophthalmometer with a tonometer. Each patient therefore has two measures – one of each observer.
