When there is enough evidence to suggest that there is likely to be a difference in groups but there is not enough evidence to predict the exact direction, the alternative nondirectional hypothesis is used. The null hypothesis assumes that there is no difference between groups, and the alternative directional hypothesis predicts the direction of the difference. The working hypothesis is a preliminary hypothesis that is subject to testing and modification.
