Summary: We studied an intervention aimed at remediating students’ tendency to interpret the area in box plots as representing the proportion or number of observations. This misinterpretation has been shown to be caused by heuristic reasoning. Using a bottom-up approach of teaching box plots, we tried to improve students’ interpretation. Most students showed improvement after the intervention, but signs of heuristic reasoning were still found. This means that under some circumstances, such as time pressure or when less attentive, these participants could still be prone to reason heuristically and hence interpret box plots incorrectly.
