Ja, és ugyanonnan még egy idézet az ilyesfajta vizsgálatokkal kapcsolatban: " Spurious associations can also easily be made, particularly when multiple hypotheses are tested. For example, one study indicated that residents of Ontario, Canada, born under the astrological sign of Leo had a higher probability of gastrointestinal hemorrhage (P=0.0447), while Sagittarians had a higher probability of humerus fracture (P=0.0123) compared to all other signs combined (these associations disappeared with proper statistical analysis). The testing of vague, non-prespecified, hypotheses increases the likelihood of that ‘something’ will be detected." |
