measure the amount of time between when the ball hits the ground to when it returns to a player’s hand.

Explanation:

The period of a repeating motion (like dribbling) is the time for one full cycle. A full dribble cycle is the ball leaving the hand, bouncing, and returning to the hand, so this interval measures one complete period of the dribble motion.

Answer:

Measure the amount of time between the basketball leaving a player's hand to the time it returns to a player's hand.
