How do you interpret a p value
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. WebJan 7, 2024 · p-value is the probability under a specified statistical model that a statistical summary of the data (for example, the sample mean difference between two compared groups) would be equal to or more extreme than its observed value
