Time Taken By Each Ball to Hit Ground
Student Ball 1 (seconds) Ball 2 (seconds) Ball 3 (seconds)
Ziva 0.52 0.51 0.51
Jade 0.51 0.52 0.52
Eduardo 0.50 0.50 0.50
Owen 0.50 0.37 0.51
Four students investigated the effect of gravity on falling objects. The students all used the same three balls and dropped them from a height of 8 meters. They recorded the time it took for each ball to hit the ground. Which student most likely had an error in the results?

Answer 1

To determine which student most likely had an error in their results, we need to analyze the recorded times for each ball.

The results are as follows:

- **Ziva**: Ball 1 = 0.52s, Ball 2 = 0.51s, Ball 3 = 0.51s
- **Jade**: Ball 1 = 0.51s, Ball 2 = 0.52s, Ball 3 = 0.52s
- **Eduardo**: Ball 1 = 0.50s, Ball 2 = 0.50s, Ball 3 = 0.50s
- **Owen**: Ball 1 = 0.50s, Ball 2 = 0.37s, Ball 3 = 0.51s

Upon reviewing their results, we can make the following observations:

- Eduardo's results are consistent, with all three balls taking the same amount of time to hit the ground (0.50s).
- Ziva and Jade have minor variations in their times but are close to each other and to Eduardo.
- Owen's time for Ball 2 (0.37s) is significantly lower than the times recorded for the other balls and by the other students. This large discrepancy suggests a possible error in measurement.

Given this analysis, it is likely that **Owen** had an error in his results, specifically with the time for Ball 2, as it stands out from the other times recorded.

So the answer is **Owen**.
