Abstract
Research that has explored students’ interpretations of graphical representations has not
extended to include how students apply understanding of particular statistical concepts
related to one graphical representation to interpret different representations. This paper
reports on the way in which students’ understanding of covariation, evidenced through their
interpretation of scatterplots, was applied to the interpretation of split stacked dot plots. The
outcomes of the study suggest that incomplete understanding of the characteristics of a
graph and the data displayed can lead to students applying knowledge of statistical concepts
relevant to one graph type to misinterpret a different graph type.
