Question

Discuss some of the advantages of using a between-subjects design

Answer 1

The major advantages of the between subjects design is that the researcher can be confident that any differences between the groups are due to the differing treatments rather than to other treatment factors that can occur when the same individual is measured more than once. That is, there are no practice, carryover, or contrast effects from exposure to multiple treatment conditions

Another advantage is that it is almost always possible to assign an individual to one of several treatment condtions...it is not always possible to expose the same individual to multiple treatment conditions.
