practice is confounded with the time of day

Explanation:

Gross motor coordination is also known as Gross motor skills, and can be described as those things that are involved in movement and coordination of the arms, legs, and other large body parts and movements.

They involve the large muscles of the body that enable such functions or activities as walking, kicking, sitting upright, lifting, and throwing a ball.

In this case, the experiment or research that the researcher is carrying out on the gross motor coordination at some specific times of the day, indicates that practice is confounded with the time of the day.
