In quantitative research, the use of a research design helps to introduce a systematic approach to the research task.
In quantitative research, the use of a research design helps to introduce a systematic approach to the research task, but does not entail openness and accountability.
Qualitative researchers do not use research designs.
Research designs are equally used in quantitative research but they vary in their particular content.
Quantitative researchers employ only fixed designs; qualitative researchers employ fixed and flexible designs.
What makes qualitative research different is not necessarily the technical construction of the design but more so its focus, application and purpose.
Grounded theory research is so named because it is ‘grounded’ on empirical data.
Grounded theory is not a ‘theory’ but a method or research design employed to generate a theory.
Theoretical sampling is any sampling procedure that is informed by an existing valid theory.
A research reaches the point of saturation when all sample units have been studied.
