Final answer:
The study mentioned uses a quantitative approach where the literature review is used to justify the study's necessity and the hypotheses being tested prior to the onset of research.
Step-by-step explanation:
In a study that is driven by a primarily quantitative approach, the literature review is conducted before the research begins. This review focuses on justifying the need for the study and the hypotheses to be tested.
The quantitative approach is systematic and empirical, relying on numerical data and statistical methods to understand phenomena and answer research questions. A well-conducted literature review in this approach ensures the study is grounded in existing knowledge and clearly communicates the rationale behind the hypotheses.
