What is an observational study?

Observational studies are ones in which researchers observe the effect of a risk factor, diagnostic test, treatment or other intervention without trying to interfere who is or isn't exposed to it. Cohort studies and case control studies are two types of observational studies.

In an observational study, we measure or survey members of a sample without trying to affect them. This is what makes it different from an experiment. In a controlled experiment, we assign people or things to groups and apply some treatment to one of the groups, when the other group does not receive the treatment.
