WebP-Value is used to perform hypothesis testing. It indicates how statistically significant a value might be. The p-value tells if a null hypothesis is valid or not. It can be measured in terms of its significance ranging from 0 to 1. … WebWe use p p -values to make conclusions in significance testing. More specifically, we compare the p p -value to a significance level \alpha α to make conclusions about our hypotheses. If the p p -value is lower than the significance level we chose, then we reject the null hypothesis H_0 H 0 in favor of the alternative hypothesis H_\text {a} H a.
