The p-value is the true test of significance
WebbIt is true that when you have a higher p-value, it’s less surprising if the results change, the effect vanishes, or even flips direction. But p-values don’t measure the probability of that happening. And a very significant p-value doesn’t indicate there is zero probability of the slope becoming negative (to use your example). Webb13 mars 2024 · As a result, the p-value has to be very low in order for us to trust the calculated metric. The lower the p-value (< 0.01 or 0.05 typically), stronger is the significance of the relationship. Also remember, the p-value is not an indicator of the strength of the relationship, just the statistical significance.

WebbThe P-value is known as the level of marginal significance within the hypothesis testing that represents the probability of occurrence of the given event. The P-value is used as an alternative to the rejection point to provide the least significance at which the null hypothesis would be rejected.
