This is easily found by using repeated measurements on the same sample performed by the same operator and using a control chart to ensure that the results are consistent. If two measurements of the same sample differ by less than the probable error, is the difference meaningful? Correction for Slope These are large errors due to careless reading of measuring instruments or faulty recording of the readings.
