Sociological Research Methods

Overview

Sociology studies social structures, institutions, relationships, and change through systematic empirical investigation. This guide covers the major research traditions — from ethnographic fieldwork to large-scale survey analysis — along with the theoretical frameworks that shape research questions. Useful for researchers designing social science studies or analyzing sociological data.

Core Theoretical Frameworks

Understanding which framework shapes your research question determines your methodology:

Framework	Core Question	Methods Favored	Key Thinkers
Structural Functionalism	How do institutions maintain social order?	Surveys, statistical analysis	Durkheim, Parsons, Merton
Conflict Theory	How does power inequality shape outcomes?	Historical analysis, critical ethnography	Marx, Weber, Bourdieu
Symbolic Interactionism	How do people construct meaning through interaction?	Ethnography, interviews, discourse analysis	Mead, Goffman, Blumer
Rational Choice	How do individuals optimize under constraints?	Formal models, experiments, survey data	Coleman, Becker
Institutional Theory	How do rules and norms shape organizational behavior?	Case studies, comparative analysis	DiMaggio, Powell, North
Network Theory	How do social connections structure opportunities?	Network analysis, graph methods	Granovetter, Burt

Qualitative Methods

Ethnography

## Ethnographic Research Design

Setting: [Where will you conduct fieldwork?]
Duration: [Minimum 6 months for deep ethnography]
Access: [How will you gain entry? Gatekeeper?]
Role: [Participant observer / Observer / Complete participant]

Data Collection:
  1. Field notes (write within 24 hours of observation)
  2. In-depth interviews (semi-structured, 60-90 min)
  3. Document analysis (institutional records, media)
  4. Photography/video (with informed consent)

Analysis:
  1. Open coding → Axial coding → Selective coding (Grounded Theory)
  2. Thematic analysis (Braun & Clarke 2006)
  3. Thick description (Geertz 1973)

In-Depth Interviews

## Interview Protocol Template

1. Opening (5 min):
   - Informed consent review
   - Recording permission
   - "Tell me about yourself and your role in [context]"

2. Core Questions (40-60 min):
   - Grand tour: "Walk me through a typical day at [setting]"
   - Specific: "Can you tell me about a time when [phenomenon]?"
   - Probe: "What did that mean to you?"
   - Contrast: "How is that different from [comparison]?"

3. Closing (10 min):
   - "Is there anything I haven't asked that you think is important?"
   - Next steps and member checking

Transcription: Verbatim, including pauses and emphasis
Sample size: Theoretical saturation (typically 15-30 interviews)

Content and Discourse Analysis

Coding Scheme Development:
1. Read 10% of corpus to identify initial themes
2. Create codebook with: code name, definition, inclusion/exclusion criteria, example
3. Double-code 20% of corpus with second researcher
4. Calculate inter-coder reliability (Cohen's κ ≥ 0.70)
5. Resolve disagreements through discussion
6. Code remaining corpus

Quantitative Methods

Survey Design

## Survey Construction Checklist

□ Define target population clearly
□ Sampling frame: how are respondents selected?
  - Probability: simple random, stratified, cluster, systematic
  - Non-probability: convenience, snowball, quota (state limitations)
□ Question types:
  - Likert scale (5-point or 7-point) for attitudes
  - Semantic differential for perceptions
  - Forced choice for behaviors
  - Open-ended for exploratory (code afterward)
□ Pilot test with 10-20 respondents from target population
□ Calculate required sample size (use G*Power or equivalent)
□ IRB/Ethics approval obtained
□ Response rate tracking plan

Common Statistical Analyses in Sociology

Analysis	When to Use	Typical Variables
Cross-tabulation + Chi-squared	Association between categories	Gender × Voting preference
Logistic regression	Binary outcome prediction	Graduated (0/1) ~ SES + Race + GPA
OLS regression	Continuous outcome	Income ~ Education + Experience + Gender
Multilevel models (HLM)	Nested data (students in schools)	Test score ~ Student vars + School vars
Structural equation modeling	Latent constructs, mediation	Self-efficacy → Achievement (mediated by effort)
Event history analysis	Time-to-event with censoring	Time to first arrest ~ Risk factors
Network analysis	Relational data	Centrality, clustering, homophily in social networks

Secondary Data Sources

Dataset	Coverage	Access	Typical Use
General Social Survey (GSS)	US attitudes since 1972	Free	Attitude trends, social change
IPUMS (Census)	US census microdata	Free (registration)	Demographics, inequality, migration
World Values Survey	100+ countries, values	Free	Cross-cultural comparison
Panel Study of Income Dynamics	US families since 1968	Free (registration)	Income mobility, poverty dynamics
European Social Survey	30+ European countries	Free	Comparative social attitudes
Add Health	US adolescents → adulthood	Application required	Health, social networks, life course
ICPSR	16,000+ social science datasets	University access	Varies by dataset

Mixed Methods Design

Sequential Explanatory:
  Phase 1: Quantitative survey (n=500) → identify patterns
  Phase 2: Qualitative interviews (n=20) → explain mechanisms

Sequential Exploratory:
  Phase 1: Qualitative fieldwork → generate hypotheses
  Phase 2: Quantitative survey → test generalizability

Concurrent Triangulation:
  Collect qualitative + quantitative simultaneously
  Compare and integrate findings
  Resolve contradictions through deeper analysis

Ethics in Social Research

## Core Principles (Belmont Report)

1. Respect for Persons: Informed consent, protect autonomy
2. Beneficence: Minimize harm, maximize benefits
3. Justice: Fair selection of subjects, equitable distribution of benefits

## Practical Requirements
□ IRB/Ethics board approval before data collection
□ Informed consent (written or verbal, documented)
□ Anonymity vs. Confidentiality (know the difference)
□ Data security: encrypted storage, access controls
□ Vulnerable populations: extra protections required
□ Right to withdraw at any time without penalty
□ Deception: only if absolutely necessary, with debriefing
