Statistical significance andPvalues have been much discussed over the past decade. In 2016, the American Statistical Association published a statement onPvalues, aiming to dispel some of the misconceptions that surround their use and interpretation1. Despite heightened attention to the misuse ofPvalues,...
In most empirical studies using null-hypothesis significance testing (NHST) that we receive, authors report only the statistical test, degrees of freedom, test value andPvalue. In some cases, we see onlyPvalues and nothing else. This extremely limited information can be misleading2 and in studie...
精读前言:本文为“Statistical Significance,p-Values, and the Reporting of Uncertainty(统计显著性、p值和不确定性的报告)”的文献精读,原文作者是Guido W. Imbens,这篇文章于2021年发表在the Journal of Economic Perspectives上,因该期刊只进行约稿,大部分文章科普性极强。其doi号为: 10.1257/jep.35.3.157. ...
Intermediate values used in calculations:t = 0.8796df = 50standard error of difference = 2.081 我输入的两组数据是 Group Group One Group Two Mean 23.7800 25.6100 SD 8.2100 6.7700 SEM 1.6420 1.3029 N 25 27 The two-tailed P value equals 0.3833 是怎么计算出来的?
5. P valuesand the search for significance Link:https://www.nature.com/articles/nmeth.4120 考虑一项研究,在100个个体中测量10个生理变量,以确定是否有任何变量可以预测收缩压(SBP)。假设所有变量在总体中都独立。如使用简单的线性回归,并关注其中一个变量作为预测变量,将在5%的样本中产生P < 0.05(图1a)。

if you are using p-values calculated for absolute difference when making an inference about percentage difference, you are likely reporting error rates which are about 50% of the actual, thus significantly overstating the statistical significance of your results and underestimating the uncertainty attach...
The American Statistical Association (ASA) has released a "Statement on Statistical Significance and P-Values" with six principles underlying the proper use and interpretation of the p-value. The ASA releases this guidance on p-values to improve the cond
