b. Because only a finite number of measurements can be made, it is possible to determine only
an estimate of random error.
Systematic error
Mean that would result from an infinite number of measurements of the same measurand carried out
under repeatability conditions minus a true value of the measurand.
Notes:
a. Systematic error is equal to error minus random error.
b. Like true value, systematic error and its causes cannot be completely known.
Correction
Value added algebraically to the uncorrected result of a m easurement to com pensate for system atic
error.
Notes:
a. The correction is equal to the negative of the estimated systematic error.
b. Since the systematic error cannot be known perfectly, the compensation cannot be complete.
Correction factor
Numerical factor by which the uncorrected result of a measurement is multiplied to compensate for
systematic error.
Note:
a. Since the systematic error cannot be known perfectly, the compensation cannot be complete.
