Verified
Random assignment of participants to conditions and experimental control of extraneous variables allows researchers to infer internal validity.
Random Assignment
A method used in experiments where participants are allocated to different groups in a way that every participant has an equal chance of being assigned to any group, ensuring variation across them.
Internal Validity
The extent to which the design and conduct of a study allow for the accurate determination of a causal relationship between variables, free from confounding factors.
Extraneous Variables
Any variable other than the independent variable that may affect the outcome of an experiment and should be controlled or accounted for.
- Recognize the necessity of managing factors like age in experimental designs to ensure internal validity.
- Differentiate the roles of independent versus dependent variables in an experimental arrangement.
