Used to identify a health problem, its characteristics, amount, distribution, occurrence of disease. Identify the cause of the health problem from determinants, such as agents, environment, and risk behaviors. 3 objectives of descriptive epidemiology: evaluate and compare trends. 2. provide a basis for planning provision of health services using data: identify problems for analytic studies, a hypothesis. 3 types of hypothesis: positive declaration (research, negative declaration (null hypothesis, implicit question (to study association) Mills 5 cannons to derive a hypothesis: method of difference, method of agreement, method of contaminant variation, method of residues, method of analogy by mac and pugh. Mills 5 cannons to derive a hypothesis: method of difference. All factors the same in 2 or more domains except one. Mills 5 cannons to derive a hypothesis: method of agreement. A single factor is common in many settings. Mills 5 cannons to derive a hypothesis: method of contaminant variation. The frequency of disease varies according to potency of a factor(cause)
