Kim, Sunjung; University Of Central Arkansas & Lombardino, Linda J.; University Of Florida
Graphs are commonly believed to facilitate users’ compre-hension. We explored the effect of graphs on comprehension compared to text, manipulating content complexity (single bar vs. double bar graphs) and question type (point-locating vs. comparison questions).
