Why is evaluating existing research a key step before conducting primary research?

Evaluating existing research is essential because it allows researchers to understand the current landscape of knowledge within a specific field. By reviewing what has already been studied, researchers can identify gaps in the literature, clarify existing findings, and ensure that their new research will add value rather than duplicate previous work. This process fosters innovation and development, as it encourages building upon established knowledge, refining methodologies, and addressing unanswered questions.

Additionally, this step aids in the formulation of relevant research questions and hypotheses, ensuring that the new study is informed by a thorough understanding of prior findings. In this way, it promotes a more efficient and effective research process, benefiting both the researchers and the broader academic community.
