Excel provides p-values for both one-tailed and two-tailed t-tests. One-tailed t-tests can detect differences between means in only one direction. For example, a one-tailed test might determine only whether Method B is greater than Method A. If it has > or < it is a one-tailed test. Back to top. One Tailed Test or Two: Onto some more technical stuff. The above should have given you a brief overview of the differences between one-tailed tests and two-tailed tests.

1 Using Excel, Chapter 8: Hypothesis Testing - One Sample Excel alone does not conduct complete hypothesis tests1. However, once you calculate the test statistic, Excel can get the critical values and the P-values needed to complete the test. The functions used to get critical values and P-values are demonstrated here. This is ONE-TAILED test, therefore the rejection region is any z-test value greater than the critical z value for a one-tailed test with alpha =.05. The critical value for one-tailed z-test at alpha =.05 is 1.645. HOW TO Find Critical Values and Rejection Regions. Therefore, the rejection region is any value GREATER than 1.645. The main difference between one-tailed and two-tailed test lies in the direction, i.e. in case the research hypothesis entails the direction of interrelation or difference, then one-tailed test is applied, but if the research hypothesis does not signifies the direction of interaction or difference, we use two-tailed test. d test.

To perform an F-Test, execute the following steps. 1. On the Data. 19/12/2018 · Learn the difference between One-tailed test and Two-tailed test to understand it better. One of the assumptions is samples have been randomly drawn from the large data. Standard P-Value is 0.05 i.e. 5%. If the variance is less than the 5% then your data is significant.
