Detailed explanation-1: -A non-directional hypothesis is a two-tailed hypothesis that does not predict the direction of the difference or relationship (e.g. girls and boys are different in terms of helpfulness).
Detailed explanation-2: -If a hypothesis does not state a direction but simply says that one factor affects another, or that there is an association or correlation between two variables then it is called a non-directional (two-tailed) hypothesis.
Detailed explanation-3: -Directional tests are known as “one-tailed” tests because all of the error is is one “tail” of the distribution (less than). Non-directional tests are called “two-tailed” tests because we must include the possibility that the alternative population could be less than m or greater than m.
Detailed explanation-4: -It involves an open-ended non-directional hypothesis that predicts that the independent variable will influence the dependent variable; however, the nature or direction of a relationship between two subject variables is not defined or clear.
