In a laboratory experiment the time it takes a marble to fall from a table to the floor is recorded with a stopwatch. The results are 0.38 seconds, 0.37 seconds and 0.39 seconds respectively. Most students in the lab believe that these times are statistically the same, within experimental error. What would be a good method to confirm the results?

A) Change the height of the table and repeat the experiment.

B) Repeat the experiment from a much higher table.

C) Repeat the experiment from a lower table.

D) Do multiple trials at the same height.
