The productions arise from the comparison of data distributions that requires relating measures of central tendency and variability in a graphical and analytical way. The results obtained were studied within the framework of the Ontosemiotic Approach to Knowledge and Mathematical Instruction, identifying the mathematical practices used with some defined skills, in the Gal’s model, as components of statistical reasoning. Most of the students carried out an analysis on the location of the mean in the distribution of the data, according to symmetry and variability, but found difficulties in evidencing the statistical knowledge skills sought in the study. Almost the total of the rest of the students correctly solved the problem, translating the graphs into frequency tables, despite the incomplete information in the graphs. The obtained results warn about aspects to consider in didactic proposals that integrate the graphic and analytical analysis of the data for the development of skills according to the statistical reasoning required in engineering students. 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.

This work presents an analysis of the resolutions of 140 students of Statistics from the Faculty of Engineering of the Universidad Nacional de Mar del Plata. The productions arise from the comparison of data distributions that requires relating measures of central tendency and variability in a graphical and analytical way. The results obtained were studied within the framework of the Ontosemiotic Approach to Knowledge and Mathematical Instruction, identifying the mathematical practices used with some defined skills, in the Gal’s model, as components of statistical reasoning. Most of the students carried out an analysis on the location of the mean in the distribution of the data, according to symmetry and variability, but found difficulties in evidencing the statistical knowledge skills sought in the study. Almost the total of the rest of the students correctly solved the problem, translating the graphs into frequency tables, despite the incomplete information in the graphs. The obtained results warn about aspects to consider in didactic proposals that integrate the graphic and analytical analysis of the data for the development of skills according to the statistical reasoning required in engineering students. |
