to keep track of an experiment
A scientist makes observations and gathers data during an experiment. If the results are inconclusive or do not support the hypothesis, they may need to repeat the experiment to verify their findings or test different variables. This iterative process is essential for ensuring accuracy and reliability in scientific research. Ultimately, a reliable conclusion can only be drawn after thorough testing and validation.
The will repeat the experiment, if they can. Sometimes with a very expensive experiment, like a drug trial, there may be steps they can take to mitigate the effects of a mistake. With the Hubble Space Telescope, for example, we were able to attach a lens to correct for a mistake in the primary mirror. Other times the experiment just has to be repeated. That is often the case anyway, as experimental results are more reliable when they are verified and corroborated by an independent group. Most scientific experiments end in failure, and sometimes external factors do show up post-research.

Well, you're going to need the right things and also you need to have experience if you are going to design an experiment.
To reduce Random and Systematic errors that may have occured during the experiment, by taking their average. This can get the most accurate value.
