The two main purposes for using repetition when conducting experiments are: reducing mistakes and increasing confidence in results

Repeating experiment is paramount as it removes any anomalous results or error.

The scientific community must be able to repeat the experiment and get the same results, which then helps to verify the accuracy of the results of the experiment.

Thus repeating experiments helps to increase the confidence in results.

reducing mistakes and increasing confidence in the results.

Explanation:

An experiment is required to be repeated so as to obtain similarities in the data observed at every trial. This indicates the correctness of the procedure applied for the process of obtaining results. This reduces the chances of mistakes in the data that can be accepted for the formulation of results with confidence.
