The question is: Scientists do their experimental tests more than once, so they can reduce the effects of chance errors. This is called conducting____________?

14 letters. Anyone know the answer?

Repeated Trails

Repeated Trials.

Nature is the entire physical universe

The answer to the question is "replication." Scientists conduct replication in their experimental tests to reduce the effects of chance errors and increase the reliability and validity of their findings. Replication involves repeating the experiment multiple times under the same conditions to determine if the results are consistent and can be replicated by other researchers. By conducting replication, scientists can increase confidence in the accuracy and generalizability of their findings.
