WebA p-value is a probability, a number between 0 and 1, calculated after running a statistical test on data. A small p-value (< 0.05 in general) means that the observed results are so … WebIf the p-value is less than the significance level, the CI will exclude zero. If the p-value equals the significance level, the end point of a CI will fall exactly on zero. If the p-value is greater than the significance level, the CI will contain zero. Let’s go to your example of a p-value of 0.1 for a mean difference between two groups.
