How would you visually represent statistical uncertainty in a chart?
Awareness that plotted points are perceived as exact truths. Replace isolated bars with intervals showing point estimate uncertainty; add hypothetical outcome plots to make values tangible. Offering p-values or raw means without visualizing uncertainty range.
Whether you understand that viewers instinctively treat drawn data points as exact truth and that omitting uncertainty distorts decisions. First, note that a standalone bar encodes false precision; second, visualize point estimate uncertainty with intervals so the audience judges overlap; third, bring in hypothetical outcome plots to animate possible values and counter static overconfidence. Red flags are citing p-values alone or claiming error bars fully solve the communication problem without discussing perceptual impact.
