Aunque su enseñanza se incluye en diversas directrices curriculares para la educación secundaria, la investigación relacionada con su comprensión es todavía escasa. Con la finalidad de identificar los conflictos semióticos en su interpretación, se presentan los resultados de un estudio de evaluación de la comprensión de este gráfico en 148 estudiantes universitarios del grado en Ciencias de la Actividad Física y del Deporte después de estudiar el tema. Se examinan las respuestas abiertas a una tarea con cuatro preguntas relacionadas con la identificación de la mediana y valores atípicos en el gráfico y la interpretación de los cuartiles y los bigotes, y se analiza el nivel de lectura que alcanzan. Los resultados muestran facilidad en la identificación de los elementos del gráfico, pero se observan conflictos semióticos relacionados con la definición y el cálculo de la mediana, así como confusión en otros conceptos.]]></p></abstract>

Although its teaching is included in various curricular guidelines for secondary education, research related to its understanding is still scarce. In order to identify semiotic conflicts in its interpretation, we present the results of a study to evaluate the understanding of this graph in 148 university students of Physical Activity and Sport Sciences after studying the subject. The open responses to a task with four questions related to the identification of the median and outliers in the graph and the interpretation of the quartiles and whiskers are analysed, looking at the reading level achieved. The results show ease of identification of the elements of the graph, although we observe semiotic conflicts related to the definition and computation of median and confusion of other concepts.]]></p></abstract>
