Document Summary
Prospective data collect data by following your reaction forward in time (in terms of the dog scenario with the tetanus shot) prospective means of or in the future : used in longitudinal research and single case experiment. Sometimes data is collected back in time retrospective data o. Eg: suppose 12 people ate at a fast food restaurant and 5 of them got food poisoning asked to figure out the reason that the 5 people became sick. The food handler may have touched some of the foods eaten while he was there that day may have passed on his germs. Can rule him out because he handled other food that day and touched more than just those items. If he were the cause (x) then others who ate at the restaurant should have become ill (y) Causality implies correlation; however, finding that x and y covary does not reveal why they are related.
