reply to discussion post: 2. In this class, you focus on using the p-value to validate a claim using a hypothesis test. This is not the only method. Research the method of critical regions to validate a claim using a hypothesis test. What is it? How does it work? Why would you use instead of or in addition to the p-value method? The critical region method in hypothesis testing defines specific ranges of values for a test statistic, called critical regions, which, if the test statistic falls within them, lead to the rejection of the null hypothesis. What is it? The critical region method, also known as the critical value approach, establishes a threshold for a test statistic based on the chosen significance level (alpha)and the distribution of the test statistic. If the calculated test statistic falls within this critical region, the null hypothesis is rejected. How does it work? Define the hypothesis, set significance level (alpha), calculate test statistic, determine critical value, compare and decide. Why would you use it? Clarity and simplicity, multiple comparison, transparency, complementary use
