Covers concrete tricks and defenses: how mean distorted by one multimillionaire makes income claims misleading, why 10 tails in a row ~1/1000 is a filmed selection rather than a miracle, how tiny samples inflate percentage claims (the 23% toothpaste example), how median vs mean vs mode change story, and chart tricks — truncated axes, cherry‑picked ranges, cumulative series, 3D pies and pictograms that exaggerate areas. Gives sample‑size, bias and repeatability checks to demand before trusting a stat.
