In statistics, a critical value is a point on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis. In a 2-tailed test, we are interested in whether the test statistic falls in the outer 5% of the distribution on both sides. To find the critical value for a 2-tailed test, you need to divide the significance level alpha by 2, since we have two tails.<\/p>\n

For example, if your significance level alpha is 0.05, you would divide 0.05 by 2 to get 0.025. You would then look up this value in a t-table or z-table, depending on the type of test you are conducting and the sample size. This will give you the critical value that you can compare to your test statistic to make a decision about the null hypothesis.<\/p>\n
