Random Error

Systematic error is a set of results of measurements that deviate by a consistent amount from the true value of the measurement. Once a systematic error is known, a correction can be applied to compensate for it.

Random error occurs when the same measurement is performed repeatedly and the resulting variations lead to the measurable values being inconsistent.
