W4 - Messay populations Flashcards
What makes data “messy”? Some groups are rare
- Some groups are rare heterogeneous or have hidden subgroupings.
- Statistical tests often fail due to non-random sampling and inconsistent variance.
Why can’t some populations be studied like typical ones?
- Lack of consent or understanding.
- Challenges in locating or studying such individuals.
What are the three main solutions for studying messy data?
Case Studies: Detailed multi-method assessments over time often focusing on unique individuals.
Small N Designs: Covered in-depth in Maree Hunt’s PSYC242 lecture.
Tests Beyond Verbal Responses: Includes Implicit Association Tests, psychophysiological/neurological measurements, and observational studies.
What are the components of a traditional case study?
- Systematic interviews and tests.
- Review of historical and factual information.
How can psychologists study populations that don’t want to participate?
- Utilize historical/factual data.
- Leverage creative non-traditional methodologies.
What tests are useful for populations with limited verbal/conscious responses?
- Implicit (automatic) reaction tests.
- Psychophysiological and neurological measurements.
How can psychologists creatively study messy populations?
- Move beyond self-report questionnaires or traditional designs.
- Use existing data in the world to generate psychological insights.
What is an example of a successful case study?
H.M. case studies which combined neurological and historical data to advance knowledge of memory.
What are the risks of case studies?
When improperly conducted they can yield inaccurate or biased conclusions.
