Resumo

Whenever one needs to classify a set of data in a given number of categories, several types of biases can occur.In order to minimize them, it's frequent to recourse to more than one judge to categorize the same data, analyzing afterwards the degree of their agreement and consequently the reliability of the classification.Among the several interrater agreement indexes mentioned in the literature, kappa coefficient (Cohen, 1960) is referred as the most frequently used when variables in study are nominal.
