Random error

Random error is the result of a single measurement of a value, minus the mean of a large number of measurements of the same value. (VIM, 3.13) Random error causes scatter in the results of a sequence of readings and, therefore, is a measure of dispersion. Random error is usually evaluated by Type A methods, but Type B methods are also used in some situations. Note: Contrary to popular belief, the GUM specifically does not replace random error with either Type A or Type B methods of evaluation. See also: error Compare with: systematic error
