Does a lower p value mean more significant
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. WebIf the p-value is less than or equal to the significance level, you reject the null hypothesis and conclude that not all population means are equal. Use your specialized knowledge …

WebAboutTranscript. We compare a P-value to a significance level to make a conclusion in a significance test. Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis. If the p value is higher than the significance level, the null hypothesis is not refuted, and the results are not statistically significant. If the p value is lower than the significance level, the results are interpreted as refuting the null hypothesis and reported as statistically significant.
