multitude of other samples. Observational error (or measurement error) is the difference between a measured value of quantity and its true value.[1] 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 how to reduce random error 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 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.

Random errors usually result from the experimenter's inability to take the same measurement in exactly the same way to get exact the same number. Systematic errors, by contrast, are reproducible inaccuracies that are consistently in the same direction. Systematic errors are often due to a problem which persists throughout the entire experiment. Note that systematic and random errors refer to problems associated with making measurements. Mistakes made in the calculations or in reading the instrument are not considered in error analysis. It is assumed that the experimenters are careful and competent! How to minimize experimental error: some examples Type of Error Example How to minimize it Random errors You measure the mass of a ring three times using the same balance and get slightly different values: 17.46 g, 17.42 g, 17.44 g Take more data. Random errors can be evaluated through statistical analysis and can be reduced by averaging over a large number of observations. Systematic errors The cloth tape measure that you use to measure the length of an object had been stretched out from years of use. (As a result, all of your length measurements were too small.)The electronic scale you use reads 0.05 g too high for all your mass measurements (because it is improperly tared throughout your experiment). Systematic errors are difficult to detect and cannot be analyzed statistically, because all of the data is off in the same direction (either to high or too low). Spotting and correcting for systematic error takes a lot of care. How would you compensate for the incorrect results of using the stretched out tape measure? How would you correct the measurements from improperly tared scale?
