1)Absolute - is measured by incidence

2)Relative= inc. of disease in persons exposed to the risk factor/
inc. of disease in persons not exposed to the fisk factor

3)Attributable= to inc. of disease in exposed persons minus the incidence of the disease in non exposed persons

the above require cohort studies

Odds ratio = odds that a case was exposed to a risk factor/ odds that a control was exposed to a risk factor (may involve case control studies and cross multiplying
