As opposed to the numerical data that is foundational, qualitative design is built on non-numerical data used to understand, construct and describe phenomena or experiences, collective or individual. Originating with the Chicago school, qualitative design has its roots firmly in anthropology and social justice, particularly for historically disenfranchised groups (Bogdan & Biklen, 2007). There have been evolving definitions of qualitative design over the last half century, however. Denzin and Lincoln’s (2011) most recent definition touches on important developments within the field:
Qualitative research is a situated activity that locates the observer in the world….[and] consists of a set of interpretive, material practices that
make the world visible….[such practices as]…fieldnotes, interviews, conversations, photographs, recordings and memos to the self.…
Qualitative researchers study things in their natural settings, attempt to make sense of, or interpret, phenomena in terms of the meanings
people bring to them. (p.3)
In qualitative research, the research is largely based on inductive reasoning, beginning with assumptions (not theory) and use interpretative and theoretical frameworks that inform their study and use the natural setting to to collect data on the people and places the phenomena occurs (Creswell & Poth, 2018).
So, simply put, qualitative design is:
It is important to note that, unlike quantitative design, the point of qualitative research is NOT to generalize across populations, but to understand the lived experience of individuals or groups within a particular cultural or social setting, system, environment or institution.
Review of the Philosophical Assumptions in Research
In qualitative research, you as the researcher are the principal instrument of inquiry. This is especially significant when considering then acknowledging your philosophical assumptions as a researcher. It is important to ask yourself (Creswell & Poth, 2018):
What are interpretative frameworks (or lenses) for Qualitative Design?
Above in the conceptual/ theoretical framework section, there is a robust discussion of conceptual vs. theoretical frameworks. It would be important to review that section. Additionally, the philosophical assumptions of a qualitative researcher are equally important and can be reviewed in the corresponding section. However, to build on the lenses discussed in previous sections, some interpretative frameworks rooted in social science as they are specifically applied to qualitative research are (Creswell & Poth, 2018; Creswell & Creswell, 2018; Bogdan & Biklen, 2007; Miles et al., 2018):
Five Kinds of Qualitative Approaches
The decision of which qualitative approach to use and which framework to use are usually determined by your research questions and are decided at the same time.
There are several different approaches to qualitative research, each approach has a specific purpose. You can narrow down your research approach by trying to understand what each approach entails and aims to understand. They are:
Narrative Research
This research is based on exploring an individual and their life. It is often a longitudinal study over many years and is a deep dive into the lives of the participant(s) in order to construct a narrative about the participant. Narrative research usually only deals with one or two people (Creswell & Poth, 2018; Creswell & Creswell, 2018; Bogdan & Biklen, 2007).
Approach: Explores situations, scenarios and processes. Data Collection: The researcher collects data from one or two subjects longitudinally. Interviews, letters, texts, documents, etc. Data Analysis: Story-telling, content review, and thematic analysis (meaning-making). Reporting Results: In-depth narration of events or situations. |
Ethnographic Research
Ethnography is concerned with describing and interpreting culture-sharing groups, as well as shared patterns groups. Drawing largely on anthropology and sociology, it uses primarily observations and interviews to find themes within and across cultural experiences (Creswell & Poth, 2018; Creswell & Creswell, 2018; Bogdan & Biklen, 2007).
Approach: Describes or interprets social grouping or cultural situations. Data Collection: Interviews, focus groups, observations, and active participation. Data Analysis: Description and interpretation of data and theme development. Reporting Results: Detailed reporting of interpretative data. |
Grounded Theory
Grounded theory deals with developing a theory grounded in data collected from the field. It is largely concerned with studying a process or action involving many individuals. The researcher states the rationale for furthering the theory, and usually, 20-60 participants' interviews are analyzed in order to advance the theory (Creswell & Poth, 2018; Creswell & Creswell, 2018; Miles et al., 2018).
Approach: Investigates procedures. Data Collection: Interviews, focus groups, and questionnaires. Data Analysis: Data coding, categorization of themes, and description of implications. Reporting Results: Theory and theoretical models. |
Phenomenology
Phenomenological approach to qualitative research is concerned with understanding participants’ shared experiences of a particular phenomenon and describing those experiences through meaning, description and search for the “essence” of the experiences (Creswell & Poth, 2018, p. 105).
Approach: Seeks to understand and explain experiences. Data Collection: Interviews, focus groups, surveys, and observations. Data Analysis: Description of experiences, examination of meaning and theme development. Reporting Results: Contextualization and reporting of experiences. |
Case Study
This approach is concerned with developing an in-depth description and analysis of a case or multiple cases. This is a departure from phenomenology, in that the “case” is a unique experience people in “a bounded system” or a “unit of inquiry” (i.e., the case) (Creswell & Poth, 2018, p.107; Yin, 2018, p. xx). The case is a novel program, unique experience, or unduplicated situation.
Approach: Examination of episodic events with a focus on answering “how” questions. Data Collection: Interviews, focus groups, observations, document content, and physical inspection. Data Analysis: Detailed description of development of themes and description of narratives. Reporting Results: In-depth study of what can be learned from case or cases. |
