Annotation: | The main characteristics of the quality of resultsmeasurements are accuracy and reliabilitywho deserve this result. Aspiringimprove the accuracy of the measurement result, we seekreduce its error (inaccuracy) and as close as possibleapproach to the true value of the measured value. Theseerrors are the result of many factors, and among theminclude: unverified measuring instruments (instruments,dishes), neattestovanenaya technique, insufficientOperator qualifications, the impact of external conditions(heat and air flow, magnetic andelectromagnetic fields, changes in atmospheric pressure,temperature and humidity, vibration, etc.). Forreduction of errors must be eliminated orreduce the impact of each of their causes.Probability theory made it possible to assess theprobable error limits beyond which they do notYou should go. This makes it possible for eachCase to choose the means and methods of measurement,providing reception result errorwhich does not exceed the borders with the requiredreliability. The reliability of measurements characterizesdegree of confidence in the measurement results. Reliabilityerror estimates are determined using the theory of lawprobability and mathematical statistics methods |
