Abstract
Esta investigación tiene como objetivo identificar y describir los errores que los estudiantes chilenos entre 8 a 9 años de edad, demuestran al construir un gráfico de barra, a partir de sus propios datos de investigación, durante una clase virtual. Este tipo de gráfico es uno de los primeros y que deben construir durante la etapa escolar. El estudio se realizó con una muestra de 14 estudiantes, los que dieron evidencia de la tarea analizada. Los resultados muestran, que la mayoría de los estudiantes se concentra en un nivel de construcción por mejorar, es decir realiza gráficos parcialmente correctos, puesto que le faltan algún elemento como rótulos o barras proporcionales. Un porcentaje no menor (36%), aún no es capaz de representar datos en el gráfico, para que estos puedan ser interpretados sin dificultades, producto de omisión del cero, ejes o una escala regresiva.

This type of graph is one of the first graphs they must construct during the school stage. The study was carried out with a sample of 14 students, who gave evidence of the task analysed. The results show that most of the students concentrate on a level of construction to be improved, i.e. they make partially correct graphs, since they are missing some element such as labels or proportional bars. A not smaller percentage (36%) is still not able to represent data on the graph so that they can be interpreted without difficulties, due to omission of zero, axes or a regressive scale.
