One Tailed And Two Tailed T Test. Choosing a one-tailed test after running a two-tailed test that failed to reject the null hypothesis is not appropriate no matter how close to significant the two-tailed test was. This table is used to find the ratio for t-statistics. μ 1 μ 2 vs. We can then see whether were in the right tail based on the sign of the test statistic.
A one-tailed test can only assess one. For example a two-tailed 2-sample t-test can determine whether the difference between group 1 and group 2 is statistically significant in either the positive or negative direction. That they differ ie. However the samples seem to be roughly similar in. Variations of the t-Test. As Glen_b mentiones in the comments.
The acquired probability is the t-curve area between the t-distribution ordinates ie the given value and infinity.

See Figure 1 b. Variations of the t-Test. A one-tailed test is a statistical test in which the critical area of a distribution is one-sided so that it is either greater than or less than a certain value but not.
