5. P值或统计显著性并不能衡量效应的大小和结果的重要性。(A p-value, or statistical significance, does not measure the size of an effect or the importance of a result. ) 某项个结果的统计显著性并不代表其在科学、人文的或者经济上的...

我们不可以单凭一个证据就毫无疑义地说原假设是错的;理论上,无论结果和原假设的差距多么大,都有可能完全是巧合。但差距越大,巧合的可能性就越小。科学家们就把发生巧合的可能性大小叫“P值”(Probability value,P-value)。 某些结果随机出现的可能性越小,p值就越低。因此,如果说读这本书没效果,而100次小测...

只要读过任何关于科学或数字的新闻报道,你基本都会遇到“统计显著性”(statistical significance)这个词。如果你误以为这个措辞意味着你读到的统计数据很显著,也是情有可原。可惜,它比这要复杂得多。根据2019 年一篇论文的定义,统计显著性的含义如下[5]:

However, when you use the numeric output produced by statistical software, youll need to compare the P value to your significance level to make this det 13、ermination. What Are P values? P-values are the probability of obtaining an effect at least as extreme as the one in your sample ...
p-value, discrete set, significance level, validity. Introduction As a consequence of Richard Anderson eschewing formal definitions, I wish to clarify our understanding of permutation procedures. A statistical procedure is said to have significance level α if one can expect the hypothesis H to be ...
