The most likely source of error in the student's experiment is:
She dropped the balls from different heights.
This would directly affect the time it takes for each ball to hit the ground, as the time of free fall is dependent on the height from which the object is dropped. The different masses of the balls should not significantly affect the fall time in a vacuum, according to the principle of gravity.
