A standard for comparison that helps to ensure that the experimental result is caused by the condition being tested is the control.
Step-by-step explanation:
In an experiment, we need to use a reference or standard term with which we compare our obtained results for better accuracy and precision. So there will several conditions or boundary conditions that need to include in those experiments to prevent the experiment from having a fallback or repair.
Among these several conditions, some of the conditions are mostly given to compare with the conditions occurred during the running of the experiment. And if any case, there is any change in those conditions with respect to standard conditions during the running of the experiment, then the experiment should be stopped.
So, these conditions which are standard comparison and helps to ensure that the experimental result is caused by the condition being tested and not anything else is termed as control.
