WebUsually distribution patterns like t distributions and z distributions are two tailed. Whereas asymmetrical distributions like Chi-square distributions and F distribution will have only one tail. One-tailed tests are also known as directional tests whereas two-tailed tests are also known as non-directional tests. WebA two-tailed test will test both if the mean is significantly greater than x and if the mean significantly less than x. The mean is considered significantly different from x if the test statistic is in the top 2.5% or bottom 2.5% of its probability distribution, resulting in a p-value less than 0.05.
