Webp-value ≤ 0.05: A p-value equal to or smaller than 0.05 indicates that the null hypothesis is probably false. Thus, there are chances of the result being more statistically significant. p-value > 0.05: On the contrary, a value exceeding 0.05 signifies that the null hypothesis seems likely, and the result may not be statistically significant. WebIf the p-value is less than alpha—the risk you’re willing to take of making a wrong decision—then you reject the null hypothesis.
