## systematic error

(engineering)
An error due to some known physical law by which it might be predicted; these errors produced by the same cause affect the mean in the same sense, and do not tend to balance each other but rather give a definite bias to the mean.
(statistics)
An error which results from some bias in the measurement process and is not due to chance, in contrast to random error.
