No. of bitstreams: 1 000018275.pdf: 4843955 bytes, checksum: 1d02ea7bf223f3701e51031ed0b82210 (MD5) Previous issue date: 1975 / This dissertation intends to be an empirical an aproach to test the validity of a mathematical model for evaluation of behavior, proposed by Ziviani (1974), in its use for evaluating and quantifying answers to multiple choice questions, the traditional model of classic psychometry standing for a criterium. It is, therefore, a comparative study between the results (scores) obtain ed by this model, and by the traditional method, in terms of the right-wrong dichotomy. It is shown how variation in the measuring instrument (test), or in measurement instruments with different characteristics, deter mines variations in scores offered by both models and that these scores are the more equivalent as the 'better' is the test from which they carne. / Esta dissertação pretende ser uma abordagem empírica para testar a validade de um modelo matemático para avaliação de comportamentos proposto por Ziviani (1974), quanto ao seu emprego para avaliar e quantificar respostas a questões de múltipla escolha, tendo como critério o modelo tradicional da psicometria clássica. É portanto, um estudo comparativo entre os resultados (escores) obtidos através deste modelo, por um lado, e através do método tradicional, em termos da dicotomia certo-errado, por outro. Visa mostrar como as variações no instrumento de medida (teste) ou instrumentos de medida com características diferentes determinam variações nos escores fornecidos pelos dois modelos e que estes escores são tanto mais equivalentes quanto 'melhor' for o teste a que se referem.
