abstract = {Common reporting styles of statistical results, such as
confidence intervals (CI), are prone to dichotomous
interpretations especially on null hypothesis testing frameworks,
for example by claiming significant differences between drug
treatment and placebo groups due to the non-overlapping CIs of
the mean effects, while disregarding the magnitudes and absolute
difference in the effect sizes. Techniques relying on the visual
estimation of the strength of evidence have been recommended to
limit such dichotomous interpretations but their effectiveness
has been challenged. We ran two experiments to compare several
visual representations of confidence intervals, and used a
Bayesian multilevel model to estimate the effects of
visualization on differences in subjective confidence of the
results. Our results suggest that adding visual information to
standard CI representation can decrease the sudden drop around
p-value 0.05 compared to standard CIs and textual representation
of CI with p-values. All data analysis and scripts are available
