A researcher investigated the effects of social facilitation on motor skills performance using a repeated measures design.
In one condition (the 'Alone' condition), participants were given 30 seconds to thread as many needles as they could while alone in a quiet room.
In a second condition (the 'Audience' condition), the same participants were given 30 seconds to thread as many needles as they could while being observed by a silent audience of four people.
The researcher recorded the number of needles successfully threaded by each participant in both conditions.
In experiments using repeated measures designs, researchers often use counterbalancing.
Explain how the researcher might have used counterbalancing in this study.
