How are directional and non-directional hypotheses different?

Directional and non-directional hypotheses are two types of hypotheses used in scientific research. A directional hypothesis predicts the direction of the relationship between variables, stating that one variable will have a specific effect on the other. In contrast, a non-directional hypothesis simply states that there will be a relationship between variables, without specifying the direction of that relationship. In other words, a directional hypothesis makes a specific prediction, while a non-directional hypothesis does not. Researchers choose between these two types of hypotheses based on their prior knowledge of the variables being studied and the specific research question being investigated.
