Ich weiß nicht, wie oft ich in Statistikbüchern die "Ausländer sind krimineller als Inländer"-Hypothese als Beispiel für einen statistischen Fehlschluss (#Simpsonsparadox) gelesen habe. Aber das scheint konservative Politiker nie davon abzuhalten aus stark aggregierten Zahlen wie der #Kriminalstatistik genau diese fragwürdigen Schlüsse zu ziehen.

The importance of visualizing data. Part 3.
Simpson's paradox is a phenomenon in statistics in which a trend appears in several groups of data but disappears or reverses when the groups are combined.

Have you heard of Simpson's Paradox?
It occurs when the relationship between variables is vastly different when the population is divided into subgroups.

This happens in various contexts and, in replying to an e-mail yesterday, I realized that it also applies to data that are analyzed spatially or temporally or when those two are pooled. Kinda cool if you're into that sort of thing. 😉
