Types of Qualitative Research

Case Study
Case Study

Qualitative case study methodology provides tools for researchers to study complex phenomena within their contexts. When the approach is applied correctly, it becomes a valuable method for health science research to develop theory, evaluate programs, and develop interventions.

Correlational (eg, Case-Control Study, Observational Study)
Correlational (eg, Case-Control Study, Observational Study)

A correlation coefficient is usually used during a correlational study. It varies between +1 and -1. A value close to +1 indicates a strong positive correlation while a value close to -1 indicates strong negative correlation.

Descriptive (eg, Case-Study, Naturalistic Observation, Survey)
Descriptive (eg, Case-Study, Naturalistic Observation, Survey)

Descriptive research methods are pretty much as they sound — they describe situations. They do not make accurate predictions, and they do not determine cause and effect. There are three main types of descriptive methods: observational methods, case-study methods and survey methods.

Ethnography
Ethnography

A qualitative "approach" is a general way of thinking about conducting qualitative research. It describes, either explicitly or implicitly, the purpose of the qualitative research, the role of the researcher(s), the stages of research, and the method of data analysis. here, four of the major qualitative approaches are introduced.

Experimental (Experiment With Random Assignment)
Experimental (Experiment With Random Assignment)

Yes, believe it or not, they are used most of the time in experimental research, even in strong experimental research! This, by the way, is not a problem if the experiment has random assignment and is replicated in different places at different times with different people.

Grounded Theory
Grounded Theory

" Grounded theory refers to a set of systematic inductive methods for conducting qualitative research aimed toward theory development. The term grounded theory denotes dual referents: (a) a method consisting of flexible methodological strategies and (b) the products of this type of inquiry.

Narrative
Narrative

Narrative research is a term that subsumes a group of approaches that in turn rely on the written or spoken words or visual representation of individuals. These approaches typically focus on the lives of individuals as told through their own stories.

Phenomenological
Phenomenological

The second step in the methodology of phenomenological research is, “bracket and interpret researcher bias and expectations” (Campbell, Introductive Methods to Qualitative Research: Course Notes, n.d., p. 4). This is identified as a best practice of the method (Campbell, Introductive Methods to Qualitative Research: Course Notes, n.d., p. 4).

Review (Literature Review, Systematic Review)
Review (Literature Review, Systematic Review)

Refers to any combination of methods where one significant component is a literature review (usually systematic). Within a review context it refers to a combination of review approaches for example combining quantitative with qualitative research or outcome with process studies.

Semi-Experimental (eg, Field Experiment, Quasi-Experiment)
Semi-Experimental (eg, Field Experiment, Quasi-Experiment)

Quasi-experimental design involves selecting groups, upon which a variable is tested, without any random pre-selection processes. For example, to perform an educational experiment, a class might be arbitrarily divided by alphabetical selection or by seating arrangement.
