The Practical Alternative to the p Value Is the Correctly Used p Value

P-value: What is and what is not

The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.    

Median of the p Value Under the Alternative Hypothesis

Due to absence of an universally acceptable magnitude of the Type I error in various Ž elds, p values are used as a wellrecognized tool in decision making in all areas of statistical practice. The distribution of p values under the null hypothesis is uniform. However, under the alternative hypothesis the distribution of the p values is skewed. The expected p value (EPV) has been proposed by aut...

Is the p value really so significant?

Interpreting the P Value

We appreciate the support of Teramoto and colleagues for the concepts outlined in our recent commentary in CHEST (August 2010), 1 which include the importance of a multidisciplinary approach to evaluating interstitial pneumonia (IP) and emphasize the usefulness of specifi c autoantibodies, such as anticyclic citrul linated peptide (CCP), as part of the assessment for connec tive tissue disease-...

The P value: probable does not mean practical.
