Summary: Six 7th-grade students engaged with an instructional sequence involving the use of the TinkerPlots software to organize data sets in ways intended to help them construe two attributes: the location of subsets of data values within a subrange of the entire set and the length of the intervals comprised by those subsets. Findings from a pretest and a culminating task suggest that the students enriched their ability to imagine and create a hypothetical data distribution from a given representative box plot, and that they became oriented to the spread of portions of a data set as indicated by the length of quartiles.
