Why is random assignment the single most important thing that an experimental designer can do?

What will be an ideal response?


May vary. Random assignment is one of three elements that must be present to
make an experiment a true experiment. Random assignment ensures that subjects are equally placed into groups without any biases. It allows researchers to know that differences at the end of the experiment can be attributed to the variations at the center of the study. It allows researchers to be more confident that the differences recorded in the experiment are caused by the treatment, not confounds.
