Is AP value of 001 statistically significant?
Most authors refer to statistically significant as P < 0.05 and statistically highly significant as P < 0.001 (less than one in a thousand chance of being wrong)….P Values.

What is a rare p-value?
When the p-value is very small, it means that the observed test statistic is very unlikely to happen if the null hypothesis is true. This gives significant evidence to suggest that the null hypothesis is false, and to reject it in favor of the alternative hypothesis.
Is a high P value good or bad?
If 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. Below 0.05, significant. Over 0.05, not significant.
What does p value tell you?
A p-value can tell you that a difference is statistically significant, but it tells you nothing about the size or magnitude of the difference. “The p-value is low, so the alternative hypothesis is true.”.
What does p value tell us?
The p-value tells us about the likelihood or probability that the difference we see in sample means is due to chance. Thus, it really is an expression of probability, with a value ranging from zero to one.
How do you explain p values?
The p-value describes how well the experiment output fits hypothesis. The hypothesis can be that the experiment output is random. The low p-values point out that the experiment output fits well with behavior predicted by the hypothesis. The higher the p-value the more the observed and predicted values differ.
What is a good p value?
Traditionally, any value under 1.0 is considered a good P/B value, indicating a potentially undervalued stock. However, value investors often consider stocks with a P/B value under 3.0.
