Reporting of the P-Value in Scientific Research P

Abstract

It is known that results of scientific research are reported using P-value in general. However, the conventional use of P values P 0.05 after statistical analysis may misleads the readers. When two studies reach the same conclusion P>0.05, but with different P values, reliability of these two studies cannot be the same though the decisions are identical. In this study, the hypothesis stating there is no difference among the surface hardness values from 3 different points of a concrete block with the dimensions 15x100x200 cm is checked. The study calls attention to the P-value and therefrom reached decision on Ho hypothesis, and the changes in the correctness levels of the mentioned decision, in the case of having different number of replications in the experiments carried out with the same objectives. As a result, it would be proper and more useful for the third parties if the P-values found with the statistical analysis were presented as exact probability values P=x.xxx
