Answer 1

1. Incidence risk is not measured by the cross sectional study .Cross sectional study are useful for characterizing the prevalence of a condition or risk factor in a particular population. Measurements are made on one patient at a specific time.

2. Case control study is used to find out the risk factors of diabetes in a population in an ethically and scientifically convincing way . Case control is one of the observational studies in which there are two groups . One group who already have the disease and another who don't have the disease . Researcher compares two groups to see any exposure was more common in the history of one group compared to another group.

3.True , the presence of disease in those who are exposed to risk factors is same as the presence of exposure to risk factor among diseased people.
