![]() ![]() ![]() When conducting a hypothesis test, we are interested in two things: the likelihood that our null hypothesis is true, and whether or not we should reject it. ![]() The critical value for a given level of significance and test statistic is found using a hypothesis testing calculator. If it is greater than or equal to the critical value, then you can reject the null hypothesis in favor of the alternative hypothesisĬritical Value Hypothesis Testing CalculatorĪ critical value is a point on the test statistic distribution that separates the region of rejection from the region of non-rejection.This can be done by looking up a z-score or t-statistic in a table, depending on what type of test you are conductingĤ) Finally, compare your calculated test statistic to the critical value.This will usually be some sort of mean or difference in meansģ) Next, you need to find the critical value.The null hypothesis is usually stated as H0, while the alternative hypothesis is typically written as H1 or HaĢ) Once you have determined the hypotheses, you need to calculate the test statistic.There are a few steps that you need to follow in order to find the critical value for hypothesis testingġ) First, you need to determine the null and alternative hypotheses. ![]()
