However Paired t test is used when you have 1 measurement variable that has two attribute out comes. So you are comparing two sets of data points. E.G- time to reach a destination when driving without drinnking and when driving after drinking.0January 15, 2008 at 1:07 pm #167217Paired t tests can be either two-tailed (nondirectional) or one-tailed (directional). Directional tests should be based on theory and/or previous research supporting this viewpoint.
