AQA GCSE Physics Paper 2 Megaset Questions 100% Acc A measurement result is considered accurate if it is judged to be close to the true value. - ANSWERAccuracy Marking a scale on a measuring instrument. This involves establishing the relationship between indications of a measuring instrument and standard or reference quantity values which must be applied. For example, placing a thermometer in melting ice to see whether it reads zero in order to check if it has been calibrated correctly. - ANSWERCalibration Information, either qualitative or quantitative, that has been collected. - ANSWERData The difference between a measured value and the true value. - ANSWERMeasurement error These are values in a set of results which are judged not to be part of the variation caused by random uncertainty. - ANSWERAnomalies These cause readings to be spread about the true value, due to results varying in an unpredictable way from one measurement to the next. Random errors are present when any measurement is made, and cannot be corrected. The effect of random urate!
