The Art of Visualizing Data: From Histograms to Box Plots
Students often conflate 'bin width' in histograms with sample size. Increasing bins reduces bias but inflates variance, leading to 'jagged' distributions. Similarly, assuming box plots represent symmetry is a trap; the whiskers can hide the distribution's modality, potentially masking a bimodal dataset as a simple symmetric one.
