What did your data show?

A. The length of the string did not affect the time it took the clip to revolve 10 times
B. The longer the string, the faster the clip completed 10 revolutions
C. The shorter the string, the faster the clip completed 10 revolutions

Without specific data, I cannot provide an accurate answer. However, if the data showed that there was no significant correlation between the length of the string and the time it took the clip to revolve 10 times, then option A would be correct. If the data showed that longer strings resulted in faster completion of 10 revolutions, then option B would be correct. On the other hand, if the data showed that shorter strings resulted in faster completion of 10 revolutions, then option C would be correct.
