Median, Understanding, University students, Semiotic conflictsAbstract
The median is a central tendency statistics widely used in exploratory data analysis and non-parametric inference, which is why its teaching is included in university statistics courses. To identify semiotic conflicts in the topic, the results of a study to evaluate the understanding of the median in 148 students of Physical Activity and Sport Sciences are presented. The open-ended responses to a questionnaire of four tasks related to the definition, calculation and properties of the median are analysed, identifying the students’ conceptual, procedural, and notational semiotic conflicts, some of which have not been described in previous research.
