- Exemplo de aplicação do coeficiente Kappa

Ana Cristina Martins (*)

RESUMO

Este artigo consiste na proposta de um procedimento alternativo ao usualmente adoptado na categorização das questões formuladas nos estudos de teste de hipóteses acerca dos outros. Em alguns deles (e.g., Devine, Hirt & Gehrke, 1990; Martins, 1996; Snyder & Swann, 1978; Swann & Giuliano, 1987), tal categorização tem oferecido dificuldades aos juízes codificadores, cuja solução adoptada se considera poder constituir uma fonte de enviesamentos. O procedimento utilizado por Martins (1995) é apresentado como uma alternativa aos das investigações anteriores, ao mesmo tempo que se discutem as suas desvantagens.

Palavras-chave: Coeficiente Kappa, Acordo inter-juízes, Acordo inter-codificadores, Codificação de dados qualitativos, Análise de Conteúdo, Teste de Hipóteses.

ABSTRACT

This article consists in the proposal of an alternative procedure to the usually adopted in the categorization of the questions formulated in the studies of hypothesis testing about the others. In some of them (e.g., Devine, Hirt & Gehrke, 1990; Martins, 1996; Snyder & Swann, 1978; Swann & Giuliano, 1987), that categorization has been offering difficulties to the judges, whose solution adopted is, here, considered as a possible source of biases. The procedure used by Martins (1995) is presented as an alternative to those of the antecedent investigations and his disadvantages are discussed.

Key words: Kappa coefficient, Inter-judges agreement, Inter-raters agreement, Codification of qualitative data, Qualitative analysis, Hypothesis testing.
