The right answer is common error.
A common error (or random error) is when, from one measure to another, the value obtained may be overvalued or underestimated in relation to the real value.
An example of a random error is the measurement of time with a timer. The error comes from the reaction time of the experimenter at start-up and at the end of the timer. Since this reaction time is not always the same, the measured value can be overestimated or underestimated. It is understandable that a repetition of the measures can alleviate the random error.
