Terminal digit preference

From HandWiki
Short description: Statistical phenomenon

Terminal digit preference, terminal digit bias, or end-digit preference is a commonly-observed statistical phenomenon whereby humans recording numbers have a bias or preference for a specific final digit in a number. In medical science, this is often seen when recording measurements such as blood pressure by hand, where those taking measurements will round to the nearest 5 or 0.[1] The phenomenon has been blamed for misdiagnoses.[2] Terminal digit bias has been used to identify errors in research,[3][4][5][6] and is one method used in the identification of scientific fraud.[7] Severe terminal digit bias has been found in datasets for scientific papers that were later retracted [8][9]
