WebThe effect of random errors can be reduced by making more or repeated measurements and calculating a new mean and/or by refining the measurement method or technique. Outliers Readings that lie a long way from other results are sometimes called outliers. Outliers must be further analysed and accounted for, rather than being automatically … When either randomness or uncertainty modeled by probability theory is attributed to such errors, they are "errors" in the sense in which that term is used in statistics; see errors and residuals in statistics. Every time we repeat a measurement with a sensitive instrument, we obtain slightly different results. The common statistical model used is that the error has two additive parts:
