Question
Which statement accurately captures why within-groups designs are preferred over between-groups designs?
Loss of participants has a more significant negative impact on between-groups designs as compared to within-groups designs.
Variability due to participants' differences is held constant across levels of the independent variable in the within-groups design, resulting in less within-groups variability.
Within-groups designs take less time than between-groups designs.
Control of extraneous variables is easier when using between-groups designs than within-groups designs.
