What p-value must be used as the Statistical Significance Threshold? P<0.005, P<0.01, P<0.05 or no value at all?

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. &nbsp; &nbsp;

Distinguishing statistical significance from clinical importance: the value of the P value.

Cost Stickiness: Value Creating or Value Destroying (The Iranian Experience)

This research reviews and tests two contradicting notions in cost stickiness literature by empirical recognition of the consequences of cost stickiness. Cost stickiness is consistent with both rational resource planning and opportunistic incentives of manager to increase personal benefits arising from status and power. Although both mechanisms involve asymmetric retention of slack, some of the ...

What is a P-value?

Results favoring one treatment over another in a randomized clinical trial can be explained only if the favored treatment really is superior or the apparent advantage enjoyed by the treatment is due solely to the working of chance. Since chance produces very small advantages often but large differences rarely, the larger the effect seen in the trial the less plausible chance assignment alone ca...

What does the p value really mean?

Consider an experiment in which 10 subjects receive a placebo, and another 10 receive an experimental diuretic. After 8 h, the average urine output in the placebo group is 769 mL, versus 814 mL in the diuretic group—a difference of 45 mL (Figure 1). How do we know if that difference means the drug works and is not just a result of chance? of 45 mL in the average urine output between groups unde...
