Description (eng)
As supplemental material, we provide (1) the raw data of estimations, (2) a video animation of the ``stretching'' of a randomly sampled dataset to achieve different correlation magnitudes, (3) boxplots showing the distributions of the participants' responses, (4) histograms of the estimations on all 72 different stimuli, (5) a bar chart displaying the number of citations of Flowers et al. (1997) since 1999, and (6) the HTML experiment framework.
