Quizplus · Accepted Answer

An epidemiological study is focused on examining the incidence, distribution, and possible control of diseases and other health factors. This type of study would be best suited for determining lifestyle factors associated with the development of asthma among American children. A double-blind study is used to reduce bias in clinical trials by blinding both the participants and the researchers to who is receiving the treatment or placebo. An in vivo study is conducted in a whole living organism, whereas a conventional study is not a recognized research method.
