Introduction
Scientific research data is widely used to characterize the laws of the objective world and production and life. Due to the uncertainty of the research object itself, human cognition
The scientific research data is uncertain due to the limitations of the measurement technology, the limitations of the means and so on. Therefore, only those who understand scientific data
Uncertainty characteristics and degrees can be used to make more accurate use of these data.
In the field of conformity assessment measurement, the measurement results are required to include information characterizing the dispersion of the results, i.e. measurement uncertainty, which has become a
consensus in the field. At present, the basic document for uncertainty assessment published by the state is GB/T 27418-2017 "Measurement uncertainty assessment and
Representation" and GB/T 27419-2018 "Measurement Uncertainty Evaluation and Representation Supplementary Document 1.Distribution Transfer Based on Monte Carlo Method"
"Broadcasting", expounds the measurement uncertainty and its evaluation principles in principle. Commonly used methods include bottom-up, top-down, and
The Carlo method.
Compared with conformity assessment measurement, scientific research involves a wider range of objects, methods, conditions, etc., and the degree of standardization is low.
Therefore, scientific research data has more complex sources of uncertainty, and it is difficult to solve various types of problems by applying existing methods in practical work.
Uncertainty assessment of scientific research data.
On the basis of classifying the characteristics of scientific research data, this document analyzes traceability data, massive data, multi-dimensional data, and repeatable test data.
Applicable methods for uncertainty assessment of data, small sample data, unknown distribution data, and qualitative data are described, including method selection, assessment
Process and application examples.
The evaluation of uncertainty is more complicated, and it is difficult to do an accurate evaluation. Measurement, observation and simulation are the main technical means of scientific research, standardization and
Quantification is an important way to ensure the quality of scientific research data.
