A school system is testing a new math teaching strategy for geometry. Ten classes were randomly selected to pilot the new strategy, and 10 classes were randomly chosen to continue using the current strategy. At the end of the school year, more than 50% of the data overlapped. Consequently, the school system could not make a determination about which teaching strategy produced higher test scores. What can the school system do to make the decision more definitive?

A) Increase the random sample size.

B) decrease the random sample size.

C) Choose the same students next year.
