Observation Study
An observational study is done by observing individuals and/or measuring a given outcome. In observational studies, no attempt is made by the researchers to intervene or alter the outcome. An example of an observational study is surveying a random group of individuals about what they eat for breakfast and determining if their breakfast habits impacted body weight.
