Abstract: The purpose of this study was to investigate what, if any relationship exists between graph construction ability and interpretation ability. Sixty-seven college students completed two graphing tasks, one involving construction and the other interpretation of graphs, both based on actual data. Statistical analysis of the scores showed no significant correlation between total scores on the two tasks and no significant relationships between specific components of graph construction ability and graph interpretation ability. These results suggest that the two abilities are distinct from one another. The study’s findings add to our understanding of graph construction ability and have practical implications for teaching and learning.
