Within Subject Design
Synonyms: Repeated-Measure Design
A study design in which each participant is studied at all levels of the independent variable that researchers can manipulate. Different conditions and outcomes are then compared within each subject to determine the effect of the manipulated variable.
The within-subjects design is also called a repeated-measure design since it involves taking repeated measurements on each subject. This design is common in psychological and biomedical research.
