To minimize random effects and the effects of uncontrolled variables by averaging multiple trials together. Why Are Multiple Trials Important In An Experiment. When we do multiple trials of the same experiment we can make sure that our results are consistent and not altered by random events.

This is due to an accumulations of errors which tend to mask the true value somewhere in a cloud of distribution of the data. Many trials are taken in an experiment as a way to limit experimental error. These are done for a couple of reasons.

Multiple trials allow you to see whether the results of each test or the trials as a whole show consistency.
