Conhecimentos de medidas de tendência central de estudantes do ensino médio: um estudo diagnóstico com foco em big data

Abstract

Given the rapid growth of data production in contemporary society, students must possess adequate skills for reading, producing, and interpreting this data. Therefore, this study sought to investigate the statistical knowledge of sophomore high school students regarding Central Tendency Measures (CTMs) imposed by the Big Data culture. The research was developed based on statistical literacy as an essential tool for students' critical thinking, using real data to develop problems. Through a questionnaire, students' skills in content related to Central Tendency Measures (CTMs) were analyzed. The results showed that, although many students master basic concepts, difficulties persist, especially with more complex mathematical operations and the interpretation of graphs and tables. On the other hand, the use of real-life situations and data from everyday life proved to be an effective way to make learning more meaningful and engaging. The analyses point to the need for pedagogical practices that engage with students' realities, promoting not only technical mastery of TCM, but also the ability to reflect, make decisions, and act consciously in the increasingly information-rich world in which we live.
