Good p values in statistics
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.
