Two-tailed hypothesis tests are also known as nondirectional and two-sided tests because you can test for effects in both directions. When you perform a two-tailed test, you split the significance level percentage between both tails of the distribution. In the example below, I use an alpha o...
Type III error: where you use a two-sided hypothesis and a corresponding two-tailed test of significance to make any declaration about the direction of a statistically significant effect. This error is not explicitly controlled, as the test is not meant to be used in such a way. Bells shoul...
The hypothesis tests can be one-tailed or two-tailed, there is no statistical way to differentiate between one tail and another, only with the interpretation of the problem we will know which tail to use to carry out the appropriate test....
Table 5 Two-sided independent-sample t-test findings comparing the unstandardized SNARC slope of left- and right-starters Full size table Furthermore, a series of two-sided Jonckheere-Terpstra tests showed no difference in unstandardized SNARC slopes based on the finger counting stability for either...
Therefore the 95% CI for the two-sided test has the form: [-0.019;0.219]. It means that the true values of the difference between the two rates vary from -0.019 to 0.219. Notice that the interval contains zero, which means that it possible that there is no difference between th...
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 both. If the sample being tested falls into the one-sided critical area, the alternative hypothesis will be accepted...

If you’re in a one-sided relationship, your partner will always avoid talking about the future. You might keep bringing up the future for the two of you, or the dreams and hopes you have of your life together in the next few years. However, when you try to discuss the future with ...
