Note(s): Bootstrapped estimates using STATA of the indirect effects of aggregated vs disaggregated graph format through the perceived trend line

The dependent variable is the likelihood of intensifying a marketing campaign investment after visualizing a graph with sales historical data, measured using a 7-point Likert scale (“1” = extremely unlikely, to “7” = extremely likely)

Judgment accuracy is a dichotomous variable that equals one if the perception of the trend line is upward and zero otherwise

Graph Format is equal to 0 when aggregated and 1 when disaggregated

The analysis reported is a structural equation model (SEM) using the variance–covariance method

The reported test of the indirect effect presents bias-corrected confidence intervals based on the results of a 1,000-repetition bootstrapping procedure

Reported p-values are two-sided
