          Abstract

          Este estudo objetivou aplicar a Teoria de Resposta ao Item na análise das 15 questões de múltipla escolha de uma prova de estatística apresentada na forma de gráficos ou de tabelas estatísticas. Participaram 413 universitários, selecionados por conveniência, de duas instituições da rede particular de ensino superior, predominantemente do curso de Psicologia (91,5%). Os universitários foram 80% do gênero feminino e do período diurno (69,8%), com idades de 16 a 53 anos, média 24,4 e desvio padrão 7,4. A prova é predominantemente unidimensional e os itens são mais bem ajustados ao modelo logístico de três parâmetros. Os índices de discriminação, dificuldade e correlação bisserial apresentam valores aceitáveis. Os resultados mostram as dificuldades apresentadas pelos estudantes com relação aos conceitos matemáticos e estatísticos, dificuldades essas observadas em outras pesquisas desde o ensino fundamental. Sugere-se que esses conceitos sejam tratados mais profundamente no ensino superior.

          Translated abstract

          This study aimed to use the Item Response Theory to analyze the 15 multiple-choice questions of a statistics test presented in the statistics graphics or tables form. The 414 university students were selected by convenience from two private universities, predominantly psychology students (91.5%). The university students were 80% female and with 16-53 years old, mean 24.4 and standard deviation 7.4. The test has predominantly one dimension and the items can be better fitting to the model of three parameters. The indexes of difficulty, discrimination and bisserial correlation presented acceptable values. The results indicate the difficulties of university students in the mathematic and statistic concepts, that difficulties are observed in the other studies since the elementary education. One suggests making more profound studies of these concepts in higher education.
