Suppose you are trying to determine the pH of a solution using pH paper. However, if we made lots of measurements, and averaged them, the mean would be an estimate of the real measurement. Estimated uncertainty in a single measurement is usually taken to be at least one-half of the smallest scale division. Q: What is a laboratory thermometer?
The Penn St... Random error can never be eliminated because instruments can never make measurements with absolute certainty. Because people's perceptions of qualitative things like color vary, the measurement of the pH would also vary between people. Sources Of Error In Physics If you mean the kind of error that is caused by a poor design of the experiment after all a human designed it then that is a systematic error.
