What Is Chosen Predominantly, and Who Chose Graphs Rather than Numbers?
We first checked whether participants in the “choice” condition were more likely to choose one of the representations by comparing the actual choice proportions with a 50/50 split, using a binomial test. Participants were generally more likely to choose the graphical representation than the numerical one. Of the 80 participants in this condition, there were 50 participants (62.5%) who chose the graphical representation but only 30 (37.5%) who chose the numerical representation, which we compared to 50% each expected by chance with a binomial test, Within the “choice” condition, we then tested whether participants who chose the graphical condition had higher graph literacy and lower numeracy scores than those who chose the numerical representation, using Participant Characteristics and Descriptive Statistics of Participants Who Chose the Numerical and Graphical Representation in the “Choice” Condition (
