Since obtaining statistical significance is easier to obtain with a directional hypothesis (one-tailed test) than with a non-directional hypothesis (two-tailed test), why would anyone ever design a study with a nondirectional hypothesis?

Answer #1

a hypothesis is a testable statement which enables one to test their predictions regarding the outcome of the study. there are two types of hypothesis. one tailed hypothesis is the one in which the nature of the effect of the independent variable to dependent variable can be predicted. two tailed hypothesis is the one in which it can be predicted that independent variable will effect the dependent variable but the direction isnt predicted. it is used when we know two groups are different but we dont know which one is better. it is used in a new and exploratory research as we are not dure of the direction of the relationship of the variables. hence people will design a non directional hypothesis in the above two cases

Directional versus nondirectional hypothesis testing. Cho and Abe (2013) provided a commentary on the appropriate use of one-tailed and two-tailed tests in behavioral research. In their discussion, they outlined the following hypothetical null and alternative hypotheses to test a research hypothesis that males self-disclose more than females: H0: µmales − µfemales ≤ 0 H1: µmales − µfemales > 0 What type of test is set up with these hypotheses, a directional test or a nondirectional test? Do these hypotheses encompass...

1.) One tailed test or two tailed test? You are performing a hypothesis test for the mean sample weight of your fellow Intro to Statistics students. For your null hypothesis , the hypothesized mean weight for the entire campus student body is 165. You have no reason to know for your alternative hypothesis whether the actual mean weight for the entire student campus body is more or less than 165. So you decide to make your alternative hypothesis as not...

What is the difference between a one-tailed test and a two-tailed test? Multiple Choice In a one-tailed test, the rejection region is in one of the tails, whereas in a two-tailed test the area of rejection is “split” between both tails of the distribution. In a one-tailed test, the rejection region is always in the upper tail, whereas in a two-tailed test the area of rejection is “split” between both tails of the distribution. In a one-tailed test, the p-value...

In a two-tailed hypothesis test of the mean using a 0.05 level of significance, researchers calculated a p-value of 0.03. What conclusion can be drawn? The alternative hypothesis should be rejected because the p-value is so small. The null hypothesis is true because the p-value is less than the level of significance. The alternative hypothesis is 3% likely to be true. The null hypothesis should be rejected because the p-value is less than the level of significance. 1.The alternative hypothesis...
