WebbIn our example, the p-value (Prob > F) is 0.0012. This small p-value can be taken as evidence that the means are not all the same. Our samples provide evidence that there is a difference in the average torque resistance values between one or more of the five lots. What is a p-value? A p-value is a measure of probability used for hypothesis testing.
