What is the primary purpose of a literature review in secondary research?

The primary purpose of a literature review in secondary research is to summarize and evaluate existing knowledge on a particular topic. This process involves systematically gathering, analyzing, and synthesizing relevant research studies, theories, and various viewpoints in the existing literature. By doing so, the literature review provides a comprehensive overview of what is already known, identifies gaps in knowledge, and can help to contextualize new research questions or findings.

A literature review is essential because it establishes a foundation upon which further research can be built. It allows researchers to understand the evolution of ideas within the field, highlight significant contributions, and recognize areas where further investigation is needed. This not only aids in clarifying the relevance of the research topic but also promotes informed discussions and decisions about future research directions.

In contrast, focusing solely on presenting original findings or creating new data sets would not align with the role of a literature review, which is intentionally retrospective and evaluative. Additionally, while theoretical frameworks are important, a literature review encompasses a broader range of content than just theory, as it integrates empirical studies, methodological discussions, and relevant critiques.
