A group of researchers is designing an experiment to test whether an herbal supplement will help people lose weight. The researchers selected a sample of 500 adults who want to lose weight, and over the next four months, 250 of them will take the herbal supplement daily whereas the remaining 250 will take a placebo daily. At the end of the four months, the researchers will compare the weight loss for the two groups.
Why is it important that the researchers use randomization to assign each of the adults who want to lose weight to a treatment group?
