ABSTRACT

Context is a key element in statistics education. The objective of this study is to examine the capacity of 14- and 15-year-old students to work with real data, analyse statistical graphs and frequency tables and interpret statistical data in its context. The results of the descriptive, exploratory analysis show that most students were correctly able to analyse and interpret data presented through statistical graphs and tables. However, some students had difficulties when it came to identifying the represented variables. More difficulties arose when calculating and interpreting means and medians — generally produced from the use of class midpoints — and making decisions. Students made little use of the context the data were presented in. Results reinforce the importance of using context in the teaching of statistics, encouraging justified decision-making.

摘要

背景是统计教育的一个关键要素。本研究的目的是检查 14 岁和 15 岁学生处理真实数据、分析统计图表和频率表以及在其背景下解释统计数据的能力。描述性、探索性分析的结果表明，大多数学生能够正确地分析和解释通过统计图表和表格呈现的数据。然而，一些学生在识别所代表的变量时遇到了困难。在计算和解释均值和中位数（通常由使用班级中点产生）和做出决定时会出现更多困难。学生很少使用数据呈现的背景。结果强调了在统计学教学中使用背景的重要性，
