Definition
Qualitative Analysis is the determination of non-numerical information about a chemical species, a reaction, etc. Examples would be observing that a reaction is creating gas that is bubbling out of solution or observing that a reaction results in a color change.
Major Approaches
There are three major approaches to qualitative research: ethnography (drawn from anthropology); phenomenology (drawn from philosophy) and grounded theory (drawn from sociology).
Grounded Theory
Grounded theory is a systematic framework involving the development of theories based on analysis of data. Participants engage in a world that requires reflexive interaction due to goals being driven by behavior relating to social interaction.
Phenomenology
A phenomenological model is a scientific model that describes the empirical relationship of phenomena to each other, in a way which is consistent with fundamental theory, but is not directly derived from theory.
Ethnography
Ethnography is a research method central to knowing the world from the standpoint of its social relations.
