Which best explains why replicating an experiment should be done by someone other than the person who originally did the experiment?

To make sure the experiment and results weren't biased

Explanation:

It shows that the experiment is designed properly.

Explanation:

Experiment refers to a scientific procedure that is carried out in order to do the demonstration of a fact already known, make discovery, or test a hypothesis to validate, refute or support it.

Any scientific experiment is expected to be subjected to a peer review in which the same experiment or technique is used by another scientist to replicate the experiment to see if they will obtain the same result obtained by the original researcher.

During the peer review, the expected result of the reviewers is the result obtained by the original researcher.

In science, it is until when the review results of different scientists are the same with that of the original researcher. i.e. the expected result, that the new idea of the original scientist is taken seriously.

If the experiment is not properly designed, the results of different scientist will be different and the experiment result will be rejected by the relevant professional body.

The aim is to show that the experiment is designed properly.
