Answer #1

When we see an ecologic study, the units of analysis are populations or groups of people rather than in a observational study where they are individuals., however noth are a type of observation only. the study group are entierly different.

An ecological fallacy is interpretation of statistical data where inferences about the nature or nature of individuals or group of study participants are deduced from inference for the group to which those individuals belong. Ecological fallacy is not subjects to a statistical issue.

Now lets think if we study mortality from cancer due to poluution in local authority areas of developing countries and developed that would be affected by it. as the nature of pollution are not same and that would cause different disease.
