Quizplus · Accepted Answer

Random error and systematic error both describe variability in test scores due to error rather than actual differences in behavior. Random error refers to the unpredictable and unsystematic variation that can occur in any measurement process, while systematic error refers to a consistent, predictable error that occurs the same way each time a measurement is made.
