Study Notes
Sampling Methods
- Convenience sampling is NOT representative of the population
Bias in Research
- Self-selection bias occurs when people choose to participate in a study, leading to biased results
WEIRD Populations
- WEIRD (Western, Educated, Industrialized, Rich, and Democratic) populations represent only 12% of the world's population but account for approximately 60% of study participants
Research Designs
Cross-Sectional Designs
- Cross-sectional designs involve collecting data from participants at a single point in time
- False: Cross-sectional designs do NOT capture data at multiple points in time
Longitudinal Designs
- Longitudinal designs involve collecting data from participants over an extended period, allowing for observation of changes over time
- False: Longitudinal designs do NOT involve collecting data at one point in time
Quasi-Experimental Designs
- Quasi-experimental designs involve non-random assignment of participants to conditions, lacking the control of true experimental designs
Experimental Designs
- False: Experimental designs DO manipulate variables to test hypotheses
Study Designs
- Within-subject designs collect data from participants relative to multiple conditions
- False: Within-subject designs do NOT collect data relative to only one condition
Best Practices in Research
- Sampling biases should always be recognized and attenuated where possible to ensure more representative results
- True: The majority of published psychological research is conducted on WEIRD samples, which may not be representative of the global population
