Enabling Students to Understand Measures of Central Tendency and Variation
Suco, Erika; Samere, Marie; Hong, Siu Lun
Mathematics Teaching, n231 p20-22 Nov 2012
Somewhere in a programme of study for mathematics in Key Stages 3 and 4 you would expect to find the terms mean, mode, median, and range. You might even find the terms central tendency, and variation. Many students following such a programme will be able to calculate the mean, most will be able to quote the mode, and some students will be able to calculate the median. While the ability to find the range for a data set will seemingly pass many learners by. And there, all too often, the story ends with no feeling for, or understanding of, the power of these measures to describe and compare datasets. Here is an approach that attempts to change the all too familiar outcomes. To enable students to understand, to interpret, and use the measures of central tendency they calculate must be the rationale that underpins and justifies the classroom time allocated to these curriculum items.
