Whenever one understands the direction to be followed in research, it is imperative to develop a directional hypothesis. This is especially in instances where there is an adequate literature review that is inclined to a specific direction. Directional hypothesis gives clear information on what the research outcomes are expected to reflect. Developing a directional hypothesis in an environment where one is capable of predicting the direction to be taken helps in ensuring one stick to that direction during his or her entire research. It facilitates in eliminating deviations during research conduction. This is because the research establishes a specific stand in his research thus strives towards proving his or her stand. Unlike unidirectional hypotheses that require one to make numerous comparisons to come up with conclusions, directional hypothesis leads to research efficiency as the required research is streamlined.
Availability of adequate literature saves one from having to conduct a lot of research to support his or her assertions. The directional hypothesis also facilitates in the accuracy of the research findings. A directional hypothesis such as “There is a significant benefit to those who go for physical exercise than to those who do not go for it,” leads to one focusing on the benefits of physical exercise rather than conducting broad research on all implications of physical exercise. Here, people already understand that the research ought to give the benefits of physical exercise. As a result, the researcher only focuses on one side of the study thus saving time. The hypothesis also helps the researcher ensure that he or she focuses on the benefits of physical exercise thus ensuring that he does not deviate from his study. This leads to one coming up with more elaborated and accurate results.
