• the p-value method • the critical value method . The p-value and critical value methods produce the same results. We will use the -pvalue method in this class. The p-value is the probability of obtaining a test statistic equal to or more extreme than the result obtained from the sample data, given that that the null hypothesis H 0 is true.

testing exist: classical or critical value, and pvalue. We will use the pvalue approach. 2. Understand the critical value for the classical approach is the same zα/2 or tα/2 used in finding Confidence Intervals. 3. Learn the pvalue as the observed significance obtained from the data. 4.

Notice that if we know the pitch (P) and the wire diameter (W), then for any particular pitch, the formula reduces to: E = M – Const where Const is a constant for a particular pitch and wire size combination. These are the constants given in the table above. Take a look at the first formula for a moment. The value 0.86603 is a constant

Plotting Positions in Extreme Value Analysis
value analysis—how to assess the correct cumulative probabilities to the ranked values—is solved. It is first shown that there exists a unique plotting formula when P, as such, is being plotted to estimate return periods. Furthermore, it is pointed out that the so-called modi-fied Gumbel method…

Using Excel, Chapter 8: Hypothesis Testing - One Sample Excel alone does not conduct complete hypothesis tests1. However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here.

8. 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).
