Experimental Research When we want to learn about the humans‚ we must experiment on the subject. There are current scientific and medical research that needs to be done on human‚ in this case there will be an experiment involving a clinical drug trial; a pharmaceutical company wants to test a new sleep aid. In order to learn more about the new sleep aid‚ researchers would need to study on patients who have trouble sleeping through the night. This can be the case of insomnia or it can be symptoms
