One way that scientists ensure that data is reliable is through?

Scientists ensure that data is reliable is through replicating experiments.

Explanation:

Scientists ensure that data is reliable enough by repeating the experiments over and over at the same physical conditions and other factors that affect the result of the experiment. The result of the experiment is recorded and evaluated to check the deviation of the results of the experiments. If the results are similar and falls within a prespecified range of the deviation, the result is considered valid. Whereas the experiments which yields much more in consistent results are considered as invalid data. In such ways, scientists ensure that the data is reliable through replicating experiments.
