Qualitative Research | Definition, Methods, and Examples

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.
