An epidemiological study is a type of observational study that looks at the frequency and distribution of diseases in different populations. It is widely used to investigate the causes and risk factors of diseases, including asthma. The scientists in this scenario want to investigate the lifestyle factors associated with the development of asthma in American children, which requires an epidemiological study. In-vivo studies involve working with living organisms, double-blind studies are often used in clinical trials to eliminate bias, and conventional studies could refer to any type of study that follows standard methods and protocols.
