It is more like trial and error. They make the experiment more accurate by the correct measurements and making sure they are using the correct equipment. When something goes wrong they simply repeat the experiment, to make the experiment improve.
To do again. Scientist repeat (do again) experiments in order to make sure the results are accurate.
When scientists make a mistake, they acknowledge it, review their methods and data, and try to identify the source of the error. They may repeat the experiment to confirm or refute their findings, and may also consult with colleagues to get their perspective on the mistake and how to correct it. Learning from mistakes is an important part of the scientific process.
If each scientist used a different system of measurement and invented their own tools of measurement, it would lead to confusion, inconsistencies, and lack of standardization in the scientific community. This would make it difficult to replicate experiments, compare results, and build upon each other's work. It would hinder progress and advancements in science.
There is a very rare possibility that a laboratory might make a mistake on DNA testing. These DNA tests are generally run along with positive and negative control reactions so that even if there were a mistake, it would clearly become evident before reporting the results. Given the importance of DNA evidence in a court of law, there are more than one lab working on the same sample so that consistent results can be obtained. DNA testing labs have to be audited and have their licences renewed every year. This processes eliminates error and reduces the possibility of erroneous results.
Scientists typically communicate the results of an experiment through scientific journals, presentations at conferences, or by publishing their findings in peer-reviewed research papers. This allows other scientists to review, replicate, and build upon the work.
fix it
When a scientist makes a mistake and has to redo an experiment, it is often referred to as a 'control experiment' or a 'repeat experiment'. This is done to ensure the accuracy and reliability of the results by verifying the consistency of the findings.
the answer is: Error
Experimental error.
redo
error
Error
It's called an error.
So they know not to make the same mistake again
To make theirs better and understand it
1. state the problem 2. gather information/research 3. make hypothesis 4. do the expiriment 5. analyze results 6. draw conclusions
