Based on the data provided, Owen shows a significant deviation in his results. Specifically, while his times for Ball 1 (0.50 seconds) and Ball 3 (0.51 seconds) are similar to the other students' results, his time for Ball 2 (0.37 seconds) is notably lower than the other recorded times for the same ball.
This unusual result likely indicates an error in Owen's measurement. Therefore, the student who most likely had an error in the results is Owen.
