systematic error [‚sis·tə′mad·ik ′er·ər] (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. How to thank TFD for its existence?
