Feedback:
A hypothesis states predicted relationships between two or more variablesthat is, the anticipated association between independent and dependent variables. Directional hypotheses predict the direction of a relationship; nondirectional hypotheses predict the existence of relationships, not their direction. Research hypotheses predict the existence of relationships; null hypotheses, which express the absence of a relationship, are the hypotheses subjected to statistical testing.
