has been defined as "any data-gathering technique that generates
narrative data (ie words) rather than numerical data (numbers)."1
The purpose of qualitative research is description/theory building,
and there are fewer controls than in quantitative research. Interviewing
and focus group discussions are ways to obtain qualitative data,

qualitative research include limited reliability (generalizability),
and difficulty in making comparisons between qualitative studies.
Also, the person collecting qualitative data must be well trained
in interviewing technique to avoid bias.
