Research Methods II

This set of flashcards covers key terms and concepts from the Research Methods II lecture, focusing on experimental designs, definitions, and methodological issues.

Independent Variable (IV)

The variable that is manipulated in an experiment to observe its effect on the dependent variable.

Dependent Variable (DV)

The variable that is measured in an experiment; it responds to the independent variable.

Random Assignment

A method used to ensure that each participant has an equal chance of being assigned to any group in an experiment.

Attribute Variable (AV)

An inherent characteristic of a participant that cannot be manipulated.

Operational Definitions

Detailed definitions of the variables used in a study, ensuring other researchers can replicate the study.

Quasi-experiment

A research design that does not involve random assignment, limiting the ability to claim causation.

Validity

The extent to which a test measures what it claims to measure.

Reliability

The consistency of a measure; a reliable measure produces the same results under consistent conditions.

Meta-analysis

A statistical technique that combines the results of multiple studies to identify overall patterns.

Causation

The action of causing something; in research, it refers to establishing a cause-effect relationship.
