N. Rico, J. F. Ruiz-Hidalgo

En una revisión de libros de texto de la asignatura de matemáticas para primero y segundo de ESO se han identificado errores en la exposición y uso de herramientas y conceptos básicos de estadística y probabilidad. Habituales en los temas de estadística descriptiva son a) ambigüedad en la definición de tipos de variables cuantitativas y cualitativas, b) confusión entre distribuciones de frecuencias y series temporales, c) selección de gráficos no adecuados para el tipo de variable en estudio, y d) confusión entre parámetro, estimador y estimación. Para los temas referentes a probabilidad se detectan con frecuencia errores como: a) ignorar las probabilidades a priori en la búsqueda de soluciones, b) ambigüedad en la diferenciación de experimento aleatorio y determinista, c) confusión entre experimento y suceso aleatorios, d) falta de descripción de los experimentos aleatorios en enunciados de problemas y e) confusión entre sucesos contrarios y complementarios.

Keywords: Alfabetización estadística, educación matemática, contenido matemático escolar, materiales curriculares
