As soon as we conduct experiments there are different variables that may influence our results, if we don’t control them. So that variable is going to be kept constant or monitored to try and minimize its influence on the experiment.
However, it is a excellent concept to comprehend the way that it works as it’s one of the easiest tests you are able to perform in hypothesis testing. It is something which the experimenter observes during an experiment and is affected by the experiment.
