Researchers wanted to investigate the efficacy of four different studying strategies, but wanted to avoid possible carryover effects. Consequently, they organized the presentation of treatments like this, and randomly assigned participants across these ordered conditions:
A) complete counterbalancing
B) a factorial design
C) partial counterbalancing
D) a Latin square design

Question

Quizplus · Accepted Answer

Partial counterbalancing is the best choice as it allows for the presentation of all treatments in different orders, while avoiding carryover effects by presenting each treatment an equal number of times at every ordinal position. This also allows for a reduced number of sequences needed compared to complete counterbalancing or a Latin square design. A factorial design would not be appropriate in this case as it would not allow for investigating the individual effects of each studying strategy.
