利用假设检验方法开展物理实验误差分析

Error Analysis of Physical Experiments by Hypothesis Testing

误差分析是物理实验数据分析过程中的一个重要环节.基于统计学中假设检验的思想,利用统计学软件IBMSPSS,将T检验的方法运用到大学物理实验的误差分析中,运用概率来说明系统误差影响的大小,提出了物理实验的误差分析方法.最后,以圆柱体直径的测量实验为例,开展了误差分析,说明了利用假设检验开展误差分析的具体流程.

Error analysis is an important step in the process of analyzing physical experimental data.Based on the idea of hypothesis testing in statistics,using the IBM SPSS,the T-test m ethod is applied to the error analysis of university physics experiments.Probability is used to explain the magnitude of the im pact of systematic errors,and an error analysis method for physics experiments is proposed.Finally,taking the measurement experiment of cylinder diameter as an example,error analysis was carried out to ilustrate the specific process of error analysis using hypothesis testing.
