Documents and artifacts in qualitative research commonly include:

• A. Medical records, diaries, photos, videos, social media text, historical documents
• B. Blood test results and lab reports
• C. Coded survey responses with numerical scales
• D. Wearable device data and sensor logs

Answer: (A)

Qualitative research relies on naturally occurring, non-numerical data that reveal people's experiences, meanings, and social processes. Documents and artifacts—such as medical records, diaries, photographs, videos, social media posts, and historical documents—provide rich material for interpretation, allowing researchers to explore narratives, practices, and contexts in depth. These sources are analyzed through methods like thematic coding, content analysis, or discourse analysis to understand how people construct reality and how social phenomena unfold over time. The other data types described are typically quantitative, offering numerical measurements from lab tests, standardized survey scales, or continuous sensor streams. Therefore, documents and artifacts are the hallmark of qualitative data sources.
