Quizplus · Accepted Answer

A one-tailed test is a directional test because it tests for the significance of a relationship in a specific direction (either positive or negative). A two-tailed test is non-directional and tests for significance in any direction. The research and null hypotheses can be directional or non-directional, depending on the specific research question and hypothesis being tested.
