Randomization: It is also useful when there is any thing or any experiment that need to be tested. because the randomization can be helpful in reducing the bias. and also it can be helpful or make easy to perform the blinding for the experiment.

control group: In any of the experiment the control group also plays very important role which allows to study only the single variable at a time. from the control group there is the possibilily to get the positive result. And also it is helpful to reduce the effect of all the variables apart from the independant variable. and is helpful in comparing the groups and may also help to evaluate and understand the interventions.
