Briefing

Qualitative research designs are practical blueprints for collecting narrative data in natural settings—so researchers can describe social phenomena in depth. The lesson frames five “giants” of qualitative inquiry—case study, ethnography, grounded theory, phenomenology, and biography/narrative research—and treats them as either designs or approaches because each guides how data is gathered and interpreted.

Case study is defined as an extensive investigation of a singular unit (“a case”), which can be an individual, group, event, process, community, or society. Its core strength is depth: it can draw on multiple data collection methods and multiple data sources, allowing researchers to retain the holistic, meaningful characteristics of real-life events.

Ethnography focuses on culture and social interaction. Rooted in cultural anthropology, it aims to understand a group’s way of life from the participants’ point of view. To do that, ethnographers study behavior in the group’s natural setting and typically rely on prolonged engagement and observational work—especially participant observation. The central question becomes identifying the group’s cultural patterns and perspectives in context.

Grounded theory addresses how theory can be generated from data rather than assumed in advance. The lesson emphasizes that researchers do not start with a fully formed theory; instead, they collect data first, then analyze it to form themes and patterns that lead to inductively derived theory. The goal is a theory “faithful to the evidence,” meaning grounded in what participants’ experiences reveal.

Phenomenology seeks the essence of lived experiences. Rather than studying a phenomenon broadly, it asks what an activity or concept feels like from participants’ perspectives. In-depth interviews are presented as the main data collection method. The lesson illustrates the design with an example: studying parents living with an autistic child may require phenomenology because those experiences are not shared by everyone, and the study aims to capture perceptions and reactions from the participants themselves.

Biography (and narrative research) centers on life experiences of an individual. Information can come from what the individual tells the researcher or from documents and archival material. The researcher then retells the information as narrative chronology. The lesson distinguishes biography from autobiography: autobiography is written by the person about their own life, while biography is written by another person about someone else’s life.

The closing guidance ties the designs together with three reminders about qualitative research design. Data collection and data analysis must proceed in close connection so meaning is not lost. Hypotheses may be generated before fieldwork, but they are not fixed and can shift as new insights emerge. Finally, data collection commonly uses three main methods: direct observation, in-depth interviews, and focus group discussions. The next lesson is set to move into mixed methods research.

Cornell Notes

Qualitative research designs provide structured ways to collect narrative data in natural settings so social phenomena can be described in depth. Five major approaches are case study, ethnography, grounded theory, phenomenology, and biography/narrative research. Case study examines a single “case” using multiple sources to preserve real-life complexity. Ethnography immerses researchers in a cultural group’s natural setting to understand patterns from participants’ viewpoints. Grounded theory builds theory inductively from data, phenomenology captures the essence of lived experience through in-depth interviews, and biography/narrative research reconstructs an individual’s life through stories and/or archival materials. These designs also share key principles: analysis must stay connected to data collection, early hypotheses can change, and common data methods include observation, interviews, and focus groups.

What makes a case study distinct among qualitative designs?

A case study is an extensive investigation of a singular unit called a “case.” That case can be an individual, group, event, process, community, or society. Its defining strength is depth: it can use multiple data collection methods and multiple data sources to explore the case while retaining the holistic, meaningful characteristics of real-life events.

How does ethnography aim to understand culture, and what data collection approach supports that goal?

Ethnography focuses on describing people’s culture and social interactions, understanding a way of life from the participants’ point of view. Because the goal is to study behavior in the group’s natural setting, the researcher needs prolonged engagement and typically relies on observational work—especially participant observation—to identify cultural patterns and perspectives.

What does “grounded in data” mean in grounded theory?

Grounded theory explicitly targets how to generate theory from research data. The lesson stresses that researchers do not begin with a fixed theory; instead, they collect data first, then analyze it to form themes and patterns. Theory is then developed inductively so it remains faithful to the evidence—meaning it reflects what participants’ experiences reveal.

Why is phenomenology especially suited to studying lived experiences that not everyone shares?

Phenomenology studies the essence of lived experiences from participants’ perspectives. The key question is what an activity or concept is like for those participants. The lesson’s example—parents living with an autistic child—illustrates the logic: experiences may be meaningful but not universally shared, so in-depth interviews help capture perceptions and reactions that others may not be able to describe.

How do biography and autobiography differ in qualitative research?

Biography studies a person’s life experiences as told to the researcher and/or drawn from documents and archival material, then retold as narrative chronology. Autobiography differs because it is written by the person themselves; biography is written by another person about someone else’s life.

What three practical reminders guide qualitative research design across these approaches?

First, data collection and data analysis must go hand in hand so the meaning of the data is not lost. Second, hypotheses may be generated before fieldwork, but they are not definite and can change during data collection as new patterns emerge. Third, data is commonly collected using three main methods: direct observation, in-depth interviews, and focus group discussions.

Review Questions

Which qualitative design would best fit a study of a cultural group’s everyday practices, and what role does participant observation play?
In grounded theory, how does theory development relate to the timing of data collection and analysis?
What distinguishes phenomenology from case study when the research goal is to understand participants’ experiences?

Key Points

1
Qualitative research designs guide how researchers collect narrative data in natural settings to describe social phenomena in depth.
2
Case study centers on a single “case” (an individual, group, event, process, community, or society) and often uses multiple data sources to preserve real-life complexity.
3
Ethnography aims to understand culture and social interaction from participants’ viewpoints, typically requiring prolonged engagement and participant observation.
4
Grounded theory builds inductively derived theory from data collected during the study, aiming for explanations “faithful to the evidence.”
5
Phenomenology targets the essence of lived experiences and commonly relies on in-depth interviews to capture participants’ perceptions.
6
Biography/narrative research reconstructs an individual’s life experiences through stories and/or archival materials, retold as narrative chronology.
7
Across designs, qualitative work depends on tight links between data collection and analysis, flexible hypotheses, and common methods such as observation, interviews, and focus groups.

Highlights

Case study is defined by depth: a thorough analysis of a single unit (“a case”) using multiple methods and sources.

Ethnography depends on immersion—prolonged time in the natural setting and participant observation—to understand culture from the inside.

Grounded theory reverses the usual order: theory is formed inductively from analyzed data rather than imposed at the start.

Phenomenology seeks the essence of lived experience, using in-depth interviews to capture perceptions that may not be shared by everyone.

Biography reconstructs a life through stories and/or documents, then organizes those accounts into narrative chronology.
