Question

Use the table of data from an investigation on the effect of gravity on falling objects to answer the question.

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?

(1 point)

Jade

Ziva

Eduardo

Owen

Answer 1

Owen — his second trial (0.37 s) is a clear outlier compared with his other times (0.50, 0.51 s) and the other students’ consistent ~0.50–0.52 s results, indicating a likely measurement error.
