Is a significance threshold needed in this study? Do you mean that you will "refuse" the hypothesis if thep-value is 0.051 and to accept the hypothesis if it is 0.049? Does it make sense in case of a studying the association between different social and demographic conditions and cancer survival? I suggest to avoid formal testing and to use p-value and confidence interval to indicate how the observed association is probably due to chance or not.
这里的相关统计知识要如何给他解答呢,他的意思是说p-value and confidence interval用来说明观察到相关的关联性并不是偶然得到的吗?
