Resumo: Este estudo teve como objetivo analisar as compreensões demonstradas por estudantes do Ensino Fundamental (5º e 7º anos), diante de distribuições univariadas e bivariadas ao levantarem hipóteses, analisarem dados e tirarem conclusões a partir da análise. Para isso, os estudantes responderam quatro atividades. Verificou-se que a maioria dos estudantes levantou hipóteses. Esse resultado é muito importante, uma vez que essa fase de uma pesquisa é fundamental. Quanto à interpretação dos dados e à confrontação entre hipóteses e dados reais, observou-se uma atitude importante dos estudantes, uma vez que os mesmos realizaram uma reanálise dos dados reais ao precisarem confrontá-los. Entretanto, na situação que envolvia a relação entre duas variáveis (distribuição bivariada) foi difícil para os estudantes de ambos os anos. Avaliação de conclusões a partir dos dados mostrou-se difícil para a maioria dos estudantes, mas não impossível. O uso de linguagem probabilística gerou dificuldades para ambos os grupos de estudantes, apesar da mesma ser necessária nas situações de incerteza. Acredita-se que intervenções pedagógicas voltadas para análise e reanálise dos dados contribuam para avanços nas compreensões dessas habilidades.Palavras-chave: Concepções estudantis; Probabilidade; Distribuição; Univariada; Bivariada. Comprehensions demonstrated by students of fundamental education in lifting hypotheses, analyzing real data and making decisionsAbstract: The purpose of this study was to analyze the understandings shown by elementary school students (5 th and 7 th years), in the face of univariate and bivariate distributions by raising hypotheses, analyzing data and drawing conclusions from the analysis. For this, the students answered four activities. It turned out that most of the students raised hypotheses. This result is very important, since this phase of a research is fundamental. As for the interpretation of the data and the confrontation between hypotheses and real data, an important attitude of the students was observed, since they realized a reanalysis of the real data when they need to confront them. However, in the situation involving the relationship between two variables (bivariate distribution) was difficult for students of both years. Evaluation of conclusions from the data proved difficult for most students, but not impossible. The use of probabilistic language generated difficulties for both groups of students, although it is necessary in situations of uncertainty. It is believed that pedagogical interventions aimed at analyzing and reanalyzing the data contribute to advances in the understanding of these skills.Keywords: Student conceptions; Probability; Distribution; Univariate; Bivariate.
