Study Notes
- There are three research designs: field, lab, and study.
- Field research is done in the natural environment of people you are studying.
- Lab research is done in a controlled setting/environment.
- Study research is not manipulated, and is usually a survey.
- There are three types of research validity: nominal, descriptive, and ordinal.
- Content validity is assessed by evidence that a measure assesses what it claims to assess.
- Reliability is assessed by freedom from error in measurement.
- The key threats to internal validity are spurious relationships and correlational research designs.
- Summarize the key facts from the text above in 10 sentences.
- Cross-sectional research is useful in identifying the causal relationship between variables, while longitudinal research is used to assess change over time.
- Random sampling leads to high external validity, while convenience sampling leads to caution regarding external validity.
- Study context also has an impact on external validity, with studies done in a limited context not being applicable to other contexts.
- Longitudinal research designs are vulnerable to threats to internal validity, including history, maturity, morality, and participant drop-out.
