(September 2016) (Learn how and when to remove https://en.wikipedia.org/wiki/Systematic_error this template message) "Measurement error" redirects here. It is not to be confused with Measurement uncertainty. A scientist adjusts an atomic force microscopy (AFM) device, which is used to measure surface characteristics and imaging http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch1/errors.html for semiconductor wafers, lithography masks, magnetic media, CDs/DVDs, biomaterials, optics, among a multitude of other samples. Observational error (or measurement error) is the difference between a measured value of quantity and its true value.[1] systematic error In statistics, an error is not a "mistake". Variability is an inherent part of things being measured and of the measurement process. Measurement errors can be divided into two components: random error and systematic error.[2] Random errors are errors in measurement that lead to measurable values being inconsistent when repeated measures of a constant attribute or quantity are taken. Systematic errors are errors that are not determined by chance systematic error definition but are introduced by an inaccuracy (as of observation or measurement) inherent in the system.[3] Systematic error may also refer to an error having a nonzero mean, so that its effect is not reduced when observations are averaged.[4] Contents 1 Overview 2 Science and experiments 3 Systematic versus random error 4 Sources of systematic error 4.1 Imperfect calibration 4.2 Quantity 4.3 Drift 5 Sources of random error 6 Surveys 7 See also 8 Further reading 9 References Overview[edit] This article or section may need to be cleaned up. It has been merged from Measurement uncertainty. There are two types of measurement error: systematic errors and random errors. A systematic error (an estimate of which is known as a measurement bias) is associated with the fact that a measured value contains an offset. In general, a systematic error, regarded as a quantity, is a component of error that remains constant or depends in a specific manner on some other quantity. A random error is associated with the fact that when a measurement is repeated it will generally provide a measured value that is different from the previous value. It is random in that the next measured value cannot be predicted exactly from previous such value
complete certainty. There is no error or uncertainty associated with these numbers. Measurements, however, are always accompanied by a finite amount of error or uncertainty, which reflects limitations in the techniques used to make them. There are two sources of error in a measurement: (1) limitations in the sensitivity of the instruments used and (2) imperfections in the techniques used to make the measurement. These errors can be divided into two classes: systematic and random. Tutorial on Uncertainty in Measurement from Systematic Errors Systematic error can be caused by an imperfection in the equipment being used or from mistakes the individual makes while taking the measurement. A balance incorrectly calibrated would result in a systematic error. Consistently reading the buret wrong would result in a systematic error. Random Errors Random errors most often result from limitations in the equipment or techniques used to make a measurement. Suppose, for example, that you wanted to collect 25 mL of a solution. You could use a beaker, a graduated cylinder, or a buret. Volume measurements made with a 50-mL beaker are accurate to within ±5 mL. In other words, you would be as likely to obtain 20 mL of solution (5 mL too little) as 30 mL (5 mL too much). You could decrease the amount of error by using a graduated cylinder, which is capable of measurements to within ±1 mL. The error could be decreased even further by using a buret, which is capable of delivering a volume to within 1 drop, or ±0.05 mL. Practice Problem 6 Which of the following procedures would lead to systematic errors, and which would produce random errors? (a) Using a 1-quart milk carton to measure 1-liter samples of milk. (b) Using a balance that is sensitive to ±0.1 gram to obtain 250 milligrams of vitamin C. (c) Using a 100-milliliter graduated cylinder to measure 2.5 milliliters of solution.
