p-value and critical value are the two approaches used to draw a conclusion in a hypothesis test. The p-value provides the probability of observing a test statistic as extreme as or more extreme than the sample result if the null hypothesis is true, while the critical value is a pre-determined threshold that separates the acceptance region of the null hypothesis from the rejection region. Depending on whether the p-value is less than the significance level or the test statistic falls in the rejection region, we either reject or fail to reject the null hypothesis.
