Read More >>>What is a 'One-Tailed 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 both. If the sample being tested falls into the one-sided critical area, the alternative hypothesis

One-Tailed and Two-Tailed Tests. The answer is that it depends on your hypothesis. When your research hypothesis states (or implies)
There's a lot of controversy around one-tail vs two-tail testing The one tailed test takes as a null hypothesis One-Tailed vs Two-Tailed Tests (Does It Matter?)

One tailed hypothesis tests. I wanted to pass along a graphic description of one tailed tests and some information regarding using Mathematica to do one-tailed tests.
Hypothesis testing involves the careful construction of two statements: the null hypothesis and the alternative hypothesis. These hypotheses can look very similar, but are actually different. How do we know which hypothesis is the null and which one is the alternative? We will see that there are a

One tailed or two tailed Hypothesis? A one-tailed directional hypothesis predicts the nature of the effect of the independent variable on the dependent variable. • E. g. : Adults will correctly recall more words than children.
Test of hypothesis (one-tail) A two tailed test of hypothesis tests the null hypothesis H0 (the 0 should be a subscript) that the mean is a specified value ( is not equal to 39 in the previous example).
