Exact confidence limits can also be easily derived for P (X > Y) and the odds of X being greater than Y. These latter two statistics can help us express t-test results in terms of differences between ...

The p-value of your AD test will indicate, with your desired level of risk, whether you can reject your null hypothesis. You need to know what that means so the next action you take is appropriate.

Calculate the p value, which is the probability of getting results like ours – if the null hypothesis is true. If p is sufficiently small, reject the null hypothesis and sound the trumpets: our effect ...

The P-value is a random variable derived from the distribution of the test statistic used to analyze a data set and to test a null hypothesis. Under the null hypothesis, the P-value based on a ...
