Panel B: Simple analysis	Z	p-value
Simple effect of graph format when visual cues are absent	−2.00	0.023
Simple effect of graph format when visual cues are present	−2.32	0.010
Simple effect of visual cues when the graph format is aggregated	−1.44	0.075
Simple effect of visual cues when the graph format is disaggregated	−0.88	0.190

Simple effect of graph format when visual cues are present	−2.32	0.010
Simple effect of visual cues when the graph format is aggregated	−1.44	0.075

Note(s): 1) The dependent variable is a dichotomous variable that equals to 1 if the perception of the trend line is upward, and 0 otherwise. 2) Graph format is equal to 0 for aggregated graph format and 1 for disaggregated graph format. 3) Visual cues is equal to 0 for the absence of visual cues and 1 for the presence of visual cues. 4) Reported significance is one-tailed for directional hypotheses
