In is common, if not standard, to interpret the results of statistical hypothesis tests using a p-value. Not all implementations of statistical tests return p-values. In some cases, you must use alternatives, such as critical values. In addition, critical values are used when estimating the expected intervals for observations from a population, such as in tolerance intervals.

In the Traditional Method, you are comparing POINTS (the Test Statistic and the Critical Value); in the P-Value Method, you are comparing AREAS (the P-Value and α (alpha)). 9. If the P-Value is less than α (alpha), reject H 0 ("If P is low, H 0 must go"). 10. The Critical Value (point) sets the boundary for α (area).About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...
