The objective of this paper is to discuss problem solving in statistical education of students in a 7th grade class, at a public school in the interior of the state of São Paulo. From a statistical research project regarding graduation parties, students should produce and analyze data which could contribute to the conduction of the event. The process was divided into the following stages: formation of groups, research of the chosen theme and its extensions; presentation of proposals and research; organization of data and preparation of graphs using an electronic spreadsheet; and presentation of results. This manner of teaching showed the importance of working with statistical education, in order to place students at the center of the teaching and learning process, the need for timely teacher guidance in each phase of the project (problematization, data collection, analysis of data and interpretation of results), and the relevance of using real data to promote moments of interaction that favor the execution of statistical procedures, appropriation of performance concepts and critical analysis based on the numerical argumentation of a theme.
