The Ongoing Tyranny Of Statistical Significance Testing
1. Statistical Significance Test (SST) and Pvalue
Stang, Poole and Kuss explain, in SST, Pvalue is an important part to decide the null hypothesis. The SST itself, they explain is analytical approach that developed based on two prominent statisticians, Fisher and the NeymanPearson. However, in present practical, SST is incompatible amalgamation of those two theories. In Fisher theory, P value represents the strength of evidence against the null hypothesis: the lower the Pvalue, the stronger the evidence. In this theory, they criticize lake of alternative hypothesis and concept of statistical power. In contrast Neyman and Person theory included the alternative for the null hypothesis, type I and II error and theoretical of effect size. This hybrid method leads to…

A Statistical Test
1277 Words  6 PagesThus, in scientific research we are looking to prove that relationships are true or to prove that they are not true. The power of a statistical test is defined as the ability of the test to lead to a conclusion to accept the HA when in fact, the HA is true (Wirtz, 2013). Also, since the probability of a statistical study depends on the prior probability, statistical power, and the level of the observed P value, it means that the probability of a study finding a true relationship is the power of 1β…
