Answer 1

1 ans -Following are factors can be considered while studying with respect to observational methods -

Public heath topics such as Adverse drug events,Antibiotic resistance, Immunization ,Obesity and Weight Management etc. or Research question such as Calculating absolute risk reduction as no treatment has been conducted? How a researcher develops design for studying the infectious agent which are prevalence ?
How can coronavirus be controlled by performing three analysis major components - sample,exposure fol lowed by outcome?

Following are factors can be considered while studying with respect to observational methods

Observational methods -Aim of observational method is to carry out non experimental studies in a systematically manner which is later compared , observed and recorded.Observational study involved in carrying on inferences between sample and population group in which independent variable are not controlled by researchers due to ethical concerns.
For example. - Effect of drug is monitor on treated group vs a control group. Randomized controlled trails ,where subject is assigned randomly to a treated group or an control group.

Types of obsrvation methods which used to obtained information while studying epidemiology are Case-Control Studies, Case-Crossover Studies , Cohort Studies and Randomized Clinical Trials .

2 ans - Type of information which can be obtained by observational methods which can be useful in understanding epidemiology is as follows-

Huge amount of questions can be understand via Observational methods. Type of observational method can be used to analysis the disease of predefined populations by studying factors such as prevalence, incidence and risk factor assossciated with diseases.Healthcare changes can be also monitored by epidmiological studies with respect to patient care.In case study of lung care,patients without lung cancer were monitored in predefined groups while to those who developed lung cancer.Researcher do the analysis by comparing the both the factors of each patitent group who are affected or not affected by lung cancer which involves - comparison between risk factor with tthe patient who smoke with patient who never smoke and develop lung cancer.Conculsion can obtained , patient who smoked developed lung cancer while patient who never smoke didnt develop lung cancer.
