📚 Quick Study Guide: Social Psychology Research Methods
- 🔬 Experimental Research: Involves manipulating one or more independent variables (IVs) to observe their effect on a dependent variable (DV), while controlling for extraneous factors. Key for establishing cause-and-effect.
- 📊 Correlational Research: Examines the relationship between two or more variables as they naturally occur. Cannot infer causation but can predict relationships. Correlation coefficient ($r$) ranges from -1.0 to +1.0.
- 📉 Survey Research: Collects data from a sample of individuals through questionnaires or interviews to describe attitudes, beliefs, or behaviors. Relies on self-report.
- 🌍 Observational Research: Systematically observes and records behavior in natural or laboratory settings. Can be participant observation or non-participant observation. Avoids self-report bias.
- 🧪 Archival Research: Analyzes existing records or documents (e.g., public records, media, historical data) to test hypotheses. Useful for studying long-term trends or events from the past.
- 🧐 Ethical Considerations: Crucial in all research. Includes informed consent, debriefing, protection from harm, confidentiality, and institutional review board (IRB) approval.
- 📈 Key Terms: Independent Variable (IV): The variable manipulated by the researcher. Dependent Variable (DV): The variable measured; the outcome. Random Assignment: Assigning participants to experimental conditions randomly to ensure groups are equivalent. Operational Definition: A clear, concise definition of a variable in terms of how it will be measured or manipulated.
