What is an ecological study?
An ecological study is a study where the level of data analysis is at a group level, rather than an individual level. So instead of individuals ranked by exposure, it is groups that are used instead.
That's right. Specifically, numbers such as mean and incidence rates are used to assess the group(s) of interest.cemsc10 wrote:yang573 wrote:Looking back at the stickied question marathon post and the first few pages, it looks like we don't have to hide questions, just answers.

Why did rates of disease transmission increase so rapidly in the first part of the 20th century?
World War I, and to a lesser extent, World War II, brought soldiers all over the world and then back home. The Spanish Flu pandemic is the most severe result of these transmissions.
