Q & A

Why are literature reviews important in data science research?

Literature reviews are important as they help clarify research aims, provide depth and breadth to subject knowledge, form theoretical frameworks for empirical investigations, and contribute to research design.

What are the key components of the literature review process?

The key components include information seeking and retrieval, evaluation, critical analysis, and synthesis.

How does one begin formulating a research strategy for a literature review?

One should start by formulating a research question or allowing the question to guide the initial search, and then define the search objectives clearly.

What are tertiary sources and why are they important in literature review?

Tertiary sources are bibliographies of bibliographies that help identify secondary sources like bibliographies, indexes, and abstracts, which are crucial for leading to primary sources for the review.

How should one approach the evaluation of sources retrieved during a literature review?

One should examine the quality of the sources based on criteria such as authority, scope, and purpose, considering the author's credibility, the publisher's reputation, and the rigor of the review process.

What does critical analysis involve when reviewing literature?

Critical analysis involves examining and analyzing the content systematically, establishing the background and justification for work, and deconstructing arguments to assess their robustness.

How can one effectively mark up and annotate a text during a literature review?

One can use underlining for claims, square brackets for reasons, asterisks or stars for evidence, and boxing for qualifiers. Highlighters and color coding can also be utilized for better visual distinction.

What is the purpose of synthesizing research in a literature review?

The purpose is to formulate a theoretical framework for one's own investigation, drawing on literature from multiple disciplines and identifying gaps in knowledge.

How should the introduction of a literature review be structured?

The introduction should include a clear statement of purpose, outlining the scope and coverage of the review, and providing reasons for the choices made during the review process.

What is the role of the conclusion in a literature review?

The conclusion should provide a clear and concise summary of the argument based on the evidence provided in the discussion, and it should end with a statement of any remaining research questions.
