RESEARCH DESIGN

3. Research is defined as the creation of new
knowledge and/or the use of existing
knowledge in a new and creative way so as to
generate new concepts, methodologies and
understandings. This could include synthesis
and analysis of previous research to the
extent that it leads to new and creative
outcomes.

18. Qualitative
Research

19. “Qualitative research is a situated activity that locates the
observer in the world. It consists of a set of interpretive,
material practices that make the world visible. These
practices…turn the world into a series of presentations,
including field notes, interviews, conversations,
photographs, recordings, and memos to the self. At this
level, qualitative research involves an interpretive,
naturalistic approach to the world. This means that
qualitative researchers study things in their natural
settings. Attempting to make sense of, or interpret
phenomena in terms of the meanings, people bring to
them.''
-Denzin and Lincoln

Both have different objectives in
healthcare, and might also be used
together and complimentarily
