Explanation: I want someone to double check my answer Cancel Post Answer Just asked! Incomplete definition (may be systematic or random) - One reason that it is impossible to make exact measurements is that the measurement is not always clearly defined. When making a measurement with a micrometer, electronic balance, or an electrical meter, always check the zero reading first. Personal Error Definition If your comparison shows a difference of more than 10%, there is a great likelihood that some mistake has occurred, and you should look back over your lab to find the
