Epidemiology is the study of how often diseases occur in different groups of people and why.

A Focus on large groups of people as individuals and relate to an audience, which can be identified. This allows statistics to be used to identifizieren.2 trends and possible causal factors. using populations where incidence of the disease and where it is unequal exposure to the suspected or possible causes.

Description. This topic has its special techniques of data collection and interpretation, and its necessary jargon of technical terms.

Implicit in any epidemiological study, the notion of a “target group” is to draw on the conclusions are. More often observations can only be on a “trial sample” , selected in any way from the target group. Systematic sampling error can be achieved by using a random selection process, in which each member of the target group has a known (non-zero) probability that can be avoided in the study sample. However, this requires Bullets or “census” of all members of the target group, the feasible may not work. Often the selection of a study sample is partially random. within the target population an accessible subset of the “study population” is defined. The study sample is then randomly selected from the study population selected this way, the people studied are two away from the group with which the study is ultimately. “target study population study sample” The definition of a study population starts with some property that all its members together, this can “geographical” (. “All inhabitants of the United Kingdom in 1985” or “all residents in a particular health district”); “professional” (“all employees of a factory”, “Children of a certain elementary school”, “all welders in England and Wales”) , (“patients on a GP list”, “residents in a nursing home”) “Special care is based on” or “diagnosis” (“all the people of Southampton, the first had an epileptic seizure in 1990 -91”) inside.
