What describes the procedures used to collect evidence in research?

The term "transparent" in this context refers to the clarity and openness of the procedures used to collect evidence in research. Transparency is crucial in research as it allows others to understand, evaluate, and replicate the methods used to gather data. When researchers are transparent, they provide detailed descriptions of their methodologies, including how they selected participants, what tools and instruments were used for data collection, and how the data was analyzed. This openness helps establish the credibility and reliability of the research findings.

In contrast, the other terms do not convey the same clarity or openness associated with effective research practices. "Opaque" suggests something that is hard to see through or understand, implying a lack of clarity in the research methods. "Ambiguous" refers to uncertainty or having multiple interpretations, which can undermine the validity of research outcomes. "Variable" indicates that something can change or differ but does not inherently relate to the clarity or specifics of evidence collection procedures. Thus, "transparent" accurately captures the essence of effective evidence collection in research.
