Answer 1

To control order effects in a repeated measures design, one should use counterbalance.

Step-by-step explanation:

To control order effects in a repeated measures design, one should use counterbalance. Counterbalancing involves systematically varying the order of treatments within a group of participants to eliminate any potential bias caused by the order of presentation. By counterbalancing, each treatment is presented in a different order for different participants, ensuring that any effects observed are not due to the order of treatments.
