# 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

```markdown
## 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

```markdown
## 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

```markdown
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

```markdown
## 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

```markdown
## 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
