AP Psychology - Research Methods Quiz

Study Notes

Hindsight Bias

Tendency to believe one knew the outcome of an event after it has occurred.
Highlights the challenge in scientific research to predict outcomes in advance.

Applied Research

Conducted to address practical problems with tangible applications.
Distinct from basic research, which focuses on theoretical questions without immediate real-world relevance.

Basic Research

Explores theoretical questions of interest to psychologists.
Aims to expand knowledge without direct application or problem-solving focus.

Hypothesis

Statement proposing a relationship between two variables.
Includes independent variable (manipulated) and dependent variable (measured).
Example: Watching violent TV is the independent variable affecting aggression (dependent variable).

Theory

Framework aimed at explaining phenomena and guiding hypothesis formulation.
Supports generation of testable hypotheses to collect data for validation.

Operational Definitions

Specific explanations detailing how variables in a study will be measured.
Essential for clarity in defining what constitutes violent programming and aggressive behavior.

Validity

Research is valid when it accurately measures what it intends to.
Important for ensuring accurate conclusions and data interpretation.

Reliability

Research reliability refers to the consistency of results across replications.
Reliable research produces similar outcomes under identical conditions.

Sampling

Involves selecting participants for research studies.
Aims to create a sample that accurately reflects the larger population for generalizability.

Population

The complete group from which a sample is drawn.
Represents anyone or anything eligible to be part of the study.

Random Selection

Method ensuring every member of the population has an equal chance of being chosen.
Enhances the representativeness of the sample and generalizability of results.

Stratified Sampling

Technique ensuring specific representation of subgroups in a sample relative to the overall population.
Useful for ensuring diverse demographic groups are proportionately included in research studies.
