Office of Health and Human Services) Epidemiology is also often called while the science of public health. It is just a quantitative willpower that is depending on current familiarity with statistics, likelihood and sound research methods. Moreover, additionally it is method of causal reasoning that develops and tests speculation defined in scientific domains like physics, behavioral savoir, biology and ergonomics. An epidemiological research is made up of the following steps: * Preliminary observation and data assortment of the population to assess the higher frequency of a particular disease or outbreak within a specific period of time. * Produce a case by simply defining the percentage of population at risk because of the certain disease. * Acquire and assess data and describe disease under analyze by means of crisis curve, area map and tabulation to exhibit the frequency rate of risk factors. * Develop hypothesis

* Conduct analytical studies by simply measuring dangers and improving hypothesis. 5. Test hypothesis and sum it up findings

5. Suggest and define affluence or preventive programs. (Health Knowledge, 2012)
