Quizplus · Accepted Answer

A one-tailed test is the best choice for testing a directional research hypothesis because it allows us to determine whether the results are significantly greater or less than what we would expect by chance in a specific direction. A two-tailed test is used for non-directional research hypotheses. Nonparametric tests and frequency tests are not appropriate for testing directional hypotheses.
