What is Controlled Experiment in PhD Thesis – A Detailed Guide blavida.com

Experimentation is a common method of studying something or exploring an issue. This method is used to establish a relationship between different variables. In different kinds of experiments, the researchers manipulate the variables and see their effect on other variables. However, in a controlled experiment, all the variables except the independent research variables are held constant. This is done so that there is no effect of external or extraneous variables on the dependent variables.
