Which feature is an advantage of using directional hypotheses?

Using a directional hypothesis provides a specific theoretical frame of reference, which means that it outlines a clear relationship or expectation between the variables being studied. This specification allows researchers to formulate precise predictions based on existing theories or prior findings. By focusing on a particular direction of the effect (e.g., whether one treatment is expected to be better than another), the researcher can employ statistical tests that are best suited to confirm or deny these specific predictions.

This clarity not only guides the research design but also aids in interpreting the results. When a directional hypothesis is confirmed, it strengthens the existing theoretical framework by offering evidence that supports the assumed relationship. Furthermore, this focused approach can enhance the validity of the findings, as they are rooted in a theoretical context that helps to explain why the expected outcomes occur.
