WebDec 2, 2024 · If your alpha level = 0.05, then your p gives you the probability for null hypothesis (the survival of the studied groups are equal). As your p = 0.052, you do not have sufficient evidence for alternative hypothesis. Also, there seems to be a risk for type II error - sample size may not be sufficient for detecting actual differences. Pore pressure gradient is a dimensional petrophysical term used by drilling engineers and mud engineers during the design of drilling programs for drilling (constructing) oil and gas wells into the earth. It is the pressure gradient inside the pore space of the rock column from the surface of the ground down to the total depth (TD), as compared to the pressure gradient of seawater in deep water. henry cody

WebBasically, a p-value of 0.052 means that if the null hypothesis is true, you have a 5.2% chance that you would get a test statistic this extreme. A p-value of 0.048 means there is a 4.8% chance. There is a 0.4 percentage point difference between the two. WebIf the p-value is less than 0.05, we reject the null hypothesis that there's no difference between the means and conclude that a significant difference does exist. If the p-value is larger than 0.05, we cannot conclude that a significant difference exists.
