Research methods and bias
Study design, validity, bias, and interpreting data.
Research methods questions test whether you can judge evidence quality. You must identify variables, recognize bias, and decide whether a study supports its conclusions.
- IV is manipulated; DV is measured
- Reliability is consistency; validity is accuracy
- Confounds weaken causal claims
- Correlation alone is not causation
- Graphs test interpretation more than calculation
Describe a study you read recently. Identify the IV, DV, and one potential confound.
