Question

Quizplus · Accepted Answer

Latin Square counterbalancing is the best choice for controlling order effects in within-subjects designs as it ensures that every treatment appears only once in any order position across the different order sequences. This reduces the likelihood of any systematic biases due to order effects and increases the internal validity of the study. Block randomization and reverse counterbalancing do not guarantee the same level of control over order effects, while complete counterbalancing may not be feasible or practical for larger designs with multiple treatments.
