1.                 One advantage of using repeated-measures designs rather than standard between-subjects designs is that:

a.                 The error SS is often smaller in repeated-measures, thereby increasing power.

b.                 Because outcome variables are correlated in repeated measures, the explained SS is higher.

c.                  Repeated measures usually have lower risk of Type I error.

d.                 Repeated measures does not have to meet all of the assumptions given for between-subjects designs.
