A method of observational study studying a disease outbreak involving interviews, studying hospital records, and gathering other points of information such as the histories of food consumed. Can be used to form a causal hypothesis that can be further tested in the future

Descriptive Epidemiology

A type of observational study using a randomly selected group of individuals to more precisely test hypotheses

Analytical Epidemiology

A type of observational study that looks to information and data from the past to gain insight into cases from the present to elucidate possible causes

Retrospective Studies

A type of observational study that assesses subjects and their disease status over the course of the study, as they go about their lives in the present rather than the past

Prospective Studies

A retrospective observational study that compares one selected group of individuals with disease to another selected, similar group without the disease. More effective than cohort studies as it uses confirmed cases within a group rather than unknown randomized subjects

Case-control Studies

Types of observational studies include:
- Descriptive epidemiology

Studies in which data is gathered from participants without manipulation by the researchers, such as through interviews. May sometimes be the only ethical option for a study. Do not necessarily prove casual relationships, only provide associations to suggest possible causes
