The Subtle Science of Misleading with Statistics

Explains concrete ways numbers mislead: swapping arithmetic/geometric/harmonic means to change a result, hiding variance so a 105 ms mean with standard deviation 4.1 vs 45 ms looks equivalent, and cherry‑picking ranges to claim no warming from 1997–2022. Shows a headline 82% claim that really comes from a tiny subgroup in a 22,500 sample, and how a log scale makes 38.3→40.1 look huge. Recommends checking ranges, sample framing, confounders and using an LLM to flag biased questions.
