In a within-subjects design, a single group of subjects is given each level of the independent variable. This means that the same group of subjects is used for all conditions, and each participant receives all levels of the independent variable. This allows for a direct comparison of the effects of the independent variable within each participant, reducing variability in the data and increasing statistical power.
