Data Collection

Collection of both quantitative and qualitative data can occur in numerous ways, varying by discipline, methodology and research design. The method of data gathering – whether from instruments, sensors, or computer system logs; by survey, interview, observation, ethnography or audio/visual recording; or otherwise – affects the research questions asked, data analysis strategies, storage and computation considerations, and more. It is a central component of data management planning.

While expertise about methodology and research design general resides within the disciplines, questions about resources such as core imaging facilities or available survey software fall squarely within the scope of Research Data Management.
