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.

The example is available in @LabPlot via File > Open Example.

@tao Thanks for this example! Great mash-up of #SimpsonsParadox and #LengthBiasedSampling

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. 😉
