Precision bias also known as numeracy bias is a form of cognitive bias in which an evaluator of information commits a logical fallacy as the result of confusing accuracy and precision. More particularly, in assessing the merits of an argument, a measurement, or a report, an observer or assessor falls prey to precision bias when they believe that greater precision implies greater accuracy (i.e., that simply because a statement is precise, it is also true); the observer or assess… WebSep 20, 2024 · Definition of Accuracy. Accuracy assesses whether a series of measurements are correct on average. For example, if a part has an accepted length of 5mm, a series of accurate data will have an average right around 5mm.
