The insignificant P value of the empirical paper is greater than or equal to 0.05, which means that the experimental results are strong evidence that the original hypothesis is not established, so the original hypothesis can be refuted with confidence. A larger P value greater than 0.05 means that there is insufficient evidence against the null hypothesis, which means that the probability of null hypothesis is too high, so the significance of empirical papers should reach 0.05 before writing.
