In this article we investigate statistical thinking manifestations revealed in the written production of students when developing a Mathematical Modeling activity. We base ourselves on theoretical contributions related to statistical thinking, associated with the idea of variation, more specifically, the production and analysis of data and the decision taken from them; to Statistics Education understood as an area concerned in the relation of the concepts of statistics and probability with other fields of knowledge, as well as with situations in which the concepts are used; and to Mathematical Modeling considered a teaching methodology in which mathematics contents emerge from a situation not essentially mathematic. We analyze an activity developed by a group of students in the context of a Mathematical Modeling discipline of the seventh period of the degree course in Mathematics of a federal university of Paraná. We use qualitative analysis to investigate students' written records, we evidence that statistical thinking is manifested from the planning of actions for the collection of data, the collection itself and the organization of these data, the interpretation of data through statistics concepts descriptions, as well as the use of different representations to think about problem.
