ABBA counterbalancing pattern is used to?

• A. Balance order effects by assigning different orders to groups
• B. Keep a single order for all participants
• C. Randomize order within each participant
• D. Omit a condition

Answer: (A)

ABBA counterbalancing is a way to control order effects in a repeated-measures design by using two fixed sequences of conditions that are assigned to different groups. In practice, one group experiences the conditions in the order A-B-B-A, while another group experiences B-A-A-B. This arrangement ensures that each condition appears in the early, middle, and late positions across participants, so any improvements from practice or fatigue are spread out rather than all piling up in the same position. That’s why it’s used to balance order effects by assigning different orders to groups. It isn’t about keeping a single order for everyone, nor about randomizing the order within each participant, and it doesn’t involve omitting any condition.
