摘要
目的:运用假设检验的方法,以确认供应商变更前后药品质量是否有显著性差异。方法:使用minitab软件,运用假设检验和p值比较法,对原料供应商变更前后的药品质量进行显著性差异分析。结果与结论:通过反复使用数理统计学中的假设检验,可以在不同显著性水平上判断数据的显著性差异,得出科学的结论,为药品生产过程中的质量保证提供科学合理的帮助。
Objective： By using hypothesis test to confirm whether there is a significant difference in drug quality before and after supplier change. Methods： The significant difference in drug quality before and after raw material supplier change was analyzed by using Minitab software, hypothesis test and the p-value comparison method. Results and Conclusion： Using hypothesis test in mathematical statistics repeatedly can judge the significant difference of data at different significance levels, draw a scientific conclusion, and offer scientific and rational help for quality assurance in the process of manufacturing practice.
