The productions arise from the comparison of data distributions that requires relating measures of central tendency and variability in a graphical and analytical way.

En este trabajo se presenta un análisis de las resoluciones de 140 estudiantes de Estadística de la Facultad de Ingeniería de la Universidad Nacional de Mar del Plata. Las producciones surgen de la comparación de distribuciones de datos que requiere relacionar medidas de tendencia central y de variabilidad en forma gráfica y analítica. Los resultados obtenidos fueron estudiados en el marco del Enfoque Ontosemiótico del Conocimiento y la Instrucción Matemática, identificando las prácticas ma- temáticas utilizadas con algunas habilidades definidas, en el modelo de Gal, como componentes del razonamiento estadístico. La mayoría de los estudiantes efectuó un análisis sobre la ubicación de la media en la distribución de los datos, según la simetría y variabilidad, pero encontró dificultades para evidenciar las habilidades del conocimiento estadístico pretendidas en el estudio. Casi el total del resto de los estudiantes, resolvió correctamente el problema, traduciendo las gráficas a tablas de frecuencias, a pesar de la información incompleta de los gráficos. Los resultados obtenidos alertan sobre aspectos a considerar en propuestas didácticas que integren el análisis gráfico y analítico de los datos para el desarrollo de habilidades acordes al razonamiento estadístico requerido en estudiantes de ingeniería.
