An experiment must have a control to show what would happen if no factors were changed.
Scientists repeat experiments for reliability. The experiment must be repeated for the scientist to develop a theory. One experiment does not prove your hypothesis correct; therefore, it must be done a several times.

The first must be inaccurate because you are sure the second results are correct.
A valid experiment is the one which is done on the basis of some facts and figures. The experiment which has a good statistical analysis is known to be valid experiment.step 3.

Your experiment must be able to be repeated so you can conduct multiple trials, thus eliminating errors. It must also be able to be replicated so other scientists can repeat it themselves.

The results of an experiment must be reproducible, meaning that they can be consistently obtained when the experiment is repeated by other researchers. Results should also be accurate, reflecting the true outcome of the experiment, and relevant to the research question being investigated. Additionally, results should be clearly presented and interpreted in the context of existing scientific knowledge.
To ensure your experiment is fair, you must keep all variables constant except for the one you are testing. This means controlling outside factors that could influence the results of your experiment.
The first must be inaccurate because you are sure the second results are correct.
