ABSTRACT

Raw data is data generated by analytical performances, including quality control checks. Reportable data or reportable results are generated from raw data by mathematical or statistical calculations. This chapter contains the duties of the analyst from the choosing of proper samples for the particular analysis through the actual analytical performance, QC checks, documentation, calculations, recognition and correction of problems, and giving the accurate, defendable result. Raw data produced by analytical performances should be converted to reportable, final results in the appropriate unit. In chemical analysis, it is often necessary to prepare calibration plots for use in calculating the results of analytical measurements. Any dilution applied during the test should be recorded and the final result will obtained by multiplying the measured value by the dilution factor. Number of significant figures refers to the number of digits reported for the value of a measured or calculated quantity indicating the accuracy or precision of the value.
