WebMore specifically, the p-value is the smallest value of α that results in the rejection of H 0. For any value of p-value > α, you fail to reject H 0, and for any value of p-value α, you reject H 0. In our t-test example, the test statistic is …
How to report that p-value = 0? Do I accept or reject the null
WebApr 24, 2024 · This was surprising, to say the least, and the p-value attached to the observation was smaller than the alpha level of p=0.0000003 that is required to announce a discovery in particle physics experiments involving collision data. The p value gets smaller as the test statistic calculated from your data gets further away from the range of test statistics predicted by the null hypothesis. The p value is a proportion: if your p value is 0.05, that means that 5% of the time you would see a test statistic at least as extreme as the one you found if the null … See more All statistical tests have a null hypothesis. For most tests, the null hypothesis is that there is no relationship between your variables of interest or that there is no difference among groups. For example, in a two-tailed t test, the … See more P values are most often used by researchers to say whether a certain pattern they have measured is statistically significant. Statistical significance is another way of saying that the p value of a statistical test is … See more The p value, or probability value, tells you how likely it is that your data could have occurred under the null hypothesis. It does this by calculating the likelihood of your test statistic, which is … See more P values are usually automatically calculated by your statistical program (R, SPSS, etc.).
