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

Answer 1

Owen

One of Owen's times (0.37 s) is a clear outlier compared with his other two measurements (0.50 and 0.51 s) and the other students' consistent values, so he most likely made an error.
