No they shoudnt have.
no. experiments should be repeatd
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.
you must repeat and redo the experiment
Scientists make more mistakes than not. It is part of the business and why they call their work "experiments". As a working scientists you try to keep your basics constant. You control the pH of your solutions, the don't switch suppliers for even basic salts mid-experiment. Most importantly you repeat experiments several times and use statistical analysis to support your conclusions. The goal of scientist is to have his/her results confirmed by repetition by others. If it isn't reproducible than it isn't believable. But wrong conclusions.... Record your mistake in the results and talk about it in the conclusion/examination of data.
They repeat them in order to try and see if it will fail. They may add or remove different variables depending on the results to see if something is effecting the experiment correctly or falsely. Start with a hypothesis and then test it and when you feel you are finished test it thats when the real testing begins.
In a science experiment you should follow established scientific protocols, ensure than your work is properly documented and publish the results so that others can repeat the experiment and verify the result.
To document the findings or document that there were no findings or that they were in conclusive
A scientists should form a hypothesis, then conduct an experiment.
They should try again. Then check very carefully and see if they did the experiment correctly. They may have to change their hypothesis.
It is important to test multiple trials of an experiment to ensure that your results are accurate, reliable, and reproducible. If you had made an error for your observations in the first trial, they should be made obvious by your observations in your second trial.
Good science is reproducible, meaning that other scientists should be able to conduct the same analysis and get similar results. If scientists try the experiments and get different results, then it often means that the original publishers did something wrong.
