Simpson s Paradox / Beck-Bornholt/Dubben: a result can be transformed into its opposite - e.g. Grouping: for reasons of prudence a new drug is given just a quarter of the patients in Old Town, while in New Town three-quarters of them get it. And that is correctly documented. - Lets suppose that the old medicine is clearly better - in the publication, both cities are thrown together - so the result is reversed. - That is often done to not expose hospitals with bad healing statistics. - Solution: division into groups. - II 200 error: e.g. old non-smokers together with young smokers.
