科学实验中常需对实验的结果进行数据分析,数据分析的准确与否直接关系到实验所得到的结论是否正确,因此数据处理对科学实验至关重要。在数据分析过程中,常用到偏差、误差和不确定度的概念,它们之间既相互联系,又有区别,因此偏差、误差和不确定度的使用极易混淆。错误使用偏差、误差和不确定度,不仅影响到数据分析的结果,甚至影响到由科 Scientific experiments often require data analysis of the experimental results, the accuracy of the data analysis is directly related to the experimental conclusion is correct, so the data processing is crucial for scientific experiments. In the process of data analysis, the concepts of deviation, error and uncertainty are often used. They are interrelated and differentiated. Therefore, the use of deviation, error and uncertainty can be easily confused. Misuse of deviations, errors and uncertainties not only affect the results of data analysis, and even affect the Section
