Quizplus · Accepted Answer

Random error refers to the natural variation or fluctuations that occur when a repeated measurement is taken. This can be caused by chance factors such as variation in the measurement tool or in the person doing the measuring. Confounding, systematic error, and time between measurements are different factors that can affect the measurement, but they do not specifically refer to random error.
