Overview
This lecture covers the differences between quantitative and qualitative research methods in sociology, their uses, advantages, and the importance of combining both for a fuller understanding of society.
Quantitative and Qualitative Data: Definitions and Differences
- Quantitative data is numerical, objective, and can be reliably analyzed for trends.
- Qualitative data is contextual, presented in words or visuals, and offers deeper insight but is more open to interpretation.
- Positivists prefer quantitative methods to observe social facts and establish patterns.
- Interpretivists use qualitative methods to understand meanings and motivations behind behavior.
Quantitative Research Methods and Uses
- Structured methods like experiments, questionnaires (with closed questions), surveys, and official statistics generate quantitative data.
- Quantitative data allows for replication, large-scale studies, and trend analysis over time and cultures.
- Governments use quantitative data for social planning, policy, and reporting (e.g., census, health, education, crime).
- Private companies and charities use unofficial statistics for marketing, funding, and media discussions.
Qualitative Research Methods and Uses
- Participant observations, unstructured interviews, open-ended questionnaires, and case studies produce qualitative data.
- Secondary sources, such as diaries, medical histories, and historical documents, offer qualitative insights.
- Ethnography uses photographs, videos, and media to gather qualitative data.
- Qualitative data is valuable for understanding minority perspectives and personal experiences.
Evaluating Methods: Suitability and Methodological Pluralism
- Structural theorists favor quantitative data for understanding broad societal patterns.
- Social action theorists use qualitative data to explore individual experiences.
- Contemporary research benefits from methodological pluralism, combining quantitative reliability with qualitative validity.
- Example: Willis’s "Learning to Labour" combines questionnaires, observations, and interviews to study working-class boys.
