Question

Quizplus · Accepted Answer

Partial counterbalancing involves randomly assigning subjects to some (but not all) of the possible treatment sequences, rather than using every possible sequence or a complete reversal of sequences. This approach is used to manage the number of treatment sequences in studies with multiple treatments, making the design more practical while still aiming to control for order effects.
