Answer #1

Non Directional Hypothesis :

A research hypothesis which does not specify the direction of expected difference or relationships is a non-directional research hypothesis.

In this cases; the difference can be in any directions.

Non Directional Hypothesis is nothing but the two-tailed test.

Example:

1. The average height of soldiers in a group is different than 175 cms.

Therefor the null and alternative Hypothesis is

v/s

2. There is no difference in the number of male and female voters in an elections.

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...
