accuracy of data definition
accuracy of data in this context means that the data does not contain any data which differs from the fact, such as time axis variation, wrong unit conversion or falsification or fabrication of data just to pass examination, and the “completeness of data” means that all data is gathered together and there is no defect or inconsistency. In addition, the “validity of data” means that the contents of the data are sufficient to achieve the results as planned.
