Due to absence of an universally acceptable magnitude of the Type I error in various fields, p values are used as a well-recognized 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 authors to be used as a measure of the performance of the test. This article proposes the median of the…

In this paper, we propose a method to choose a test result from several competing ones. The choice is based on the p value under the alternative, i.e., the probability of obtaining an extreme or a
Confusion surrounding the reporting and interpretation of results of classical statistical tests is widespread among applied researchers. The confusion stems from the fact that most of these

A new method based on the information about the distribution of p-values is presented and discussed in this article as well as classical methods such as Bonferroni correction and the Bonferronsi-Holm method which account for the multiple testing issue and consequently improve reliability of change detection.

This chapter demystifies P-values, hypothesis tests and significance tests and introduces the concepts of local evidence and global error rates, which are useful indices of evidence and deserve their place in the statistical toolbox of basic pharmacologists.

Reproducibility is the essence of a scientific research. Focusing on two-sample problems we discuss in this paper the reproducibility of statistical test results based on p-values. First,
It is shown that P-values quantify experimental evidence not by their numerical value, but through the likelihood functions that they index.
In this paper, we provide a practical method on how to calculate pValue for continuous data. In later paper, we will cover pValue for discrete data. For continuous distribution in part 1, we defined
