Two-tailed tests are used when the alternative hypothesis is non-directional. 1. A non-directional hypothesis states that a population parameter(such as a mean or regression coefficient) is not equal to a certain value (such as 0). Two-tailed tests are appropriate for most studies. 2. If you’re calculating a confidence … See more The degrees of freedom (df) of a statistic are calculated from the sample size (n).
