摘　　要：提出一种基于相关度的大学物理实验数据评估方法,该方法通过大学生所测物理量的测量值范围与该物理量的参考值范围进行相关比较,采用相关度来评估大学生的物理实验数据测量情况。根据不同测量情况下,测量值范围与参考值范围之间的关系,推导出了相应的相关度公式,给出了一个由相关度和评分制所构成的测量成绩评分公式。理论分析和实验结果说明了该方法的合理性。An evaluation method on measured data in college physical experiment is put forward,in which the measured value range is correlated with reference value range for the same measurement,the degree of correlation is employed to evaluate the physical experimental data measured by university student.The formula for degree of correlation is derived from the relationship between measured value range and reference value range and the evaluation formula constructed with degree of correlation and scoring system is given.Theoretical analysis and experimental results show that the evaluation method is reasonable.

关 键 词：物理实验数据评估 相关度 测量值范围 参考值范围
