Abstract

This paper is about classroom use of technologies for teaching and learning data analysis, in particular relationships to do with box plots. I describe technology based instruction that mediated understanding of median and quartile values, spread, and recognition of variation between box plots for samples from the same population. Statistical analysis using box plots incorporates all three aspects but hinges on the third. Research shows that many students base analysis on median, quartile and extreme values only. However, curricula that centre on sampling, and where technologies are used strategically, seem to have the most potential for encouraging multifaceted analysis of data using box plots.
