  2. Hypotheses 1 How is this disease distributed? 2 Is there an association? Did the exposure and the disease turn up together? 3 Is the association causal? 4 What should be done to prevent the disease? 5 Did the prevention strategy work? Where are we and where are we going? What’s my hypothesis? Detectives in the Classroom - Investigation 2-7: Epi Team Challenge
