Mechanisms¶
- Diagnostic Plot Review
- … the cheapest possible guard against reporting a precise-looking result built on a fit that never held. Anscombe's quartet — four datasets with identical means, variances, and regression lines but wildly different shapes — is the standing proof that you cannot trust summary statistics without looking at the picture.
This sourceIt is the canonical demonstration that summary statistics can hide the very structure a plot makes obvious.

- Residual Divergence Map
- Its failure mode is over-reading the picture — mistaking a rendering or scaling artifact for a real boundary, or seeing structure in what is actually noise, the visual analogue of finding faces in clouds. Anscombe's quartet
