correlation/descriptive study
case studies or naturalistic observation
- examine the degree to which two or more variables are related (knowing one may allow
- can be used to pridect behaviouroutcomes
- can’t say why an association exists you to predict the value of another)
- not necessarily measures cause and effect
reseach designs
- experimental
- correlational
- longitudinal
- descriptive

case studies
- appropriate for unusual cases
- difficult to generalise
- difficult to determine cause and effect
internal validity
whether a study accurately measures a causal relationship and the cause/effect relationship given by the study cannot be given by other factor
external validity
whether the findings can be applied to a broader population
correlation
when changes in one variable are accompanied by changes in another
natural observation
- high external validity
- can generate new ideas
- time consuming and you may not observe what you want to
- low internal validity (can’t control confounds)
- cause and effect difficult to establish
- usually small and may not be representative
common issues in research
- bias (subject vs researcher expectancies; sampling bias)
- correlation vs causation
- confounding variables
key ethical principles
- protection from physical/psychological harm
- informed consent
- confidentiality
- deception and debriefing
- children or vulnerable people as subjects
