A within-subjects design is more efficient when the number of available subjects is relatively small because it allows us to gather more information from each individual subject, making better use of our limited pool of participants. Additionally, a within-subjects design is more effective when individual differences are relatively large because it helps to control for these differences by using each participant as their own control, making it easier to identify the effects of the independent variable on the dependent variable.
