You can distinguish between correlation and causation and eliminate confounding variables by using random assignment. Experiments often create contrasts between a control group and one or more treatment groups as a crucial part of the scientific method.
<h3>When is random assignment appropriate in an experiment?</h3>
In general, whenever it is ethically feasible and appropriate for your research topic, random assignment should always be used in trials. Both random sampling and random assignment are crucial ideas in research, but it's critical to recognize their distinctions.
<h3>Is it moral to choose participants for an experiment at random?</h3>
