El análisis e interpretación de gráficos estadísticos requiere, entre otros elementos, del conocimiento numérico, que se muestra de muy variadas formas en las actividades estadísticas. Se presenta un estudio preliminar cuyo objetivo es analizar cómo se utiliza la razonabilidad numérica para argumentar las respuestas a actividades estadísticas, cuya información se ofrece a través de gráficos. Se analizan las respuestas de 110 estudiantes a un cuestionario escrito en el que se ha contrastado sus repuestas en cuanto al nivel de argumentaciones estadística y numérica. Se ha encontrado que la mayoría de los estudiantes cometen errores de cálculo, o simplemente no utilizan la información numérica, en situaciones donde son requeridas basando las argumentaciones de sus respuestas en justificaciones contextuales poco elaboradas o en intuiciones personales.

A preliminary study is presented whose objective is to analyze how numerical reasonableness is used to argue the answers to statistical activities, whose information is offered through graphs. The answers of 110 students are analyzed to a written questionnaire in which their answers have been compared in terms of the level of statistical and numerical argumentations. It has been found that most students make calculation errors, or simply do not use the numerical information, in situations where they are required. They base the arguments of their answers in little elaborated contextual justifications or in personal intuitions.
