What is Qualitative Research?

Qualitative research is a method of inquiry that aims to understand human behavior and the reasons that govern such behavior. It involves collecting non-numeric data, such as words, images, or objects, to gain insights into people's attitudes, behaviors, value systems, concerns, motivations, aspirations, culture, or lifestyles. 

Unlike quantitative research, which seeks to quantify the data and generalize results from a sample to the population of interest, qualitative research focuses on exploring phenomena in their natural settings, providing a deep, contextual understanding of the subject matter.

Comparison with Quantitative Research

Qualitative and quantitative research are two fundamental approaches to gathering and analyzing data. Here are some key differences and complementarities:

  • Nature of Data: Qualitative research collects non-numeric data (e.g., interviews, observations), while quantitative research collects numeric data (e.g., surveys, experiments).
  • Objective: The goal of qualitative research is to understand concepts, thoughts, or experiences, whereas quantitative research aims to quantify the problem and understand how prevalent it is by looking at statistical relationships.
  • Approach: Qualitative research is more subjective and uses methods like interviews, focus groups, and ethnography. Quantitative research is more objective and uses methods like surveys, longitudinal studies, and statistical analysis.
  • Outcome: Qualitative research provides depth of understanding and detailed insights into the subject, while quantitative research provides breadth of understanding and statistical validation.

Despite these differences, both methods are complementary. Quantitative research can validate findings from qualitative research, and qualitative research can provide context and depth to findings from quantitative research.

Historical Background

The roots of qualitative research can be traced back to early anthropological and sociological studies.

  • Early Beginnings: In the late 19th and early 20th centuries, researchers like Franz Boas and Bronisław Malinowski used ethnographic methods to study cultures and societies, laying the groundwork for qualitative research.
  • Development: During the mid-20th century, qualitative research gained prominence in various social sciences. The Chicago School of Sociology, for instance, emphasized the importance of studying people in their natural environments.
  • Modern Era: In the 1960s and 1970s, qualitative research methods were further developed and formalized, with significant contributions from scholars like Clifford Geertz, who introduced the concept of "thick description" in ethnography.
  • Recent Trends: Today, qualitative research is widely used across disciplines, including psychology, education, health sciences, and market research, employing advanced techniques and tools to gather and analyze data.

Qualitative research offers a comprehensive approach to understanding human experiences and social phenomena. Exploring the depths of people's perspectives, it provides invaluable insights that complement quantitative data, leading to a holistic understanding of the research topic.

Key Characteristics of Qualitative Research

Qualitative research possesses unique attributes that distinguish it from other research methodologies.


Qualitative research places a strong emphasis on subjectivity, aiming to understand the individual experiences and perspectives of participants. This approach recognizes that people's perceptions and interpretations of their experiences are valid data sources. Researchers immerse themselves in the participants' world, often using open-ended questions and interactive methods to capture the depth and complexity of human experiences.

Contextual Understanding

A crucial aspect of qualitative research is its focus on the context and environment in which the phenomena occur. By situating the study within the real-life settings of participants, researchers can gain a deeper understanding of the social, cultural, and environmental factors that influence behaviors and attitudes. This contextual understanding is essential for interpreting the findings accurately and meaningfully.


Qualitative research is inherently flexible, allowing researchers to adapt their study design and methods as the research progresses. This adaptability is crucial for exploring complex and dynamic social phenomena. Researchers often employ iterative processes, where data collection and analysis occur simultaneously, enabling them to refine their research questions and methods based on emerging insights. This flexibility ensures that the research remains relevant and responsive to the participants' realities.

Rich Data

One of the hallmark characteristics of qualitative research is the collection of detailed and rich descriptive data. This data often includes in-depth interviews, participant observations, field notes, and visual materials, providing a comprehensive view of the studied phenomena. The richness of qualitative data allows for a nuanced analysis, revealing patterns, themes, and insights that might be overlooked in quantitative research. This depth of understanding is invaluable for developing theories, informing policy, and guiding practice in various fields.

Qualitative Research Methods

Qualitative research employs a variety of methods to gather in-depth and detailed data about human experiences and social phenomena.


Interviews are a fundamental method in qualitative research, allowing researchers to collect detailed personal accounts from participants. There are three main types of interviews:

  • Structured Interviews: These follow a strict script of predetermined questions, ensuring consistency across all participants.
  • Semi-Structured Interviews: These have a flexible structure, with key questions guiding the conversation but allowing for follow-up questions based on participants' responses.
  • Unstructured Interviews: These are the most flexible, resembling a natural conversation, with topics emerging organically. Conducting effective interviews involves building rapport, asking open-ended questions, and actively listening to gather rich, insightful data.
