True or false: Confounding only needs to be considered in analytic epidemiologic studies.
Homework Answers
Confounding is referred to as mixing the exposure on the risk of disease with third factor that distort the risk ratio. This confound has a complex relationship with both exposure and disease that cause this ratio distortion.
Confounding is to be considered in analytical epidemiological studies because these studies deal with researching the cause of disease. Considering confounding only in analytical epidemiological studies is a false statement as it has to be considered in even experimental, observational and quasi experimental studies.

True or False The epidemiologic triangle is the only way to model the spread of infectious disease. Herd immunity must be at 100% to protect the group. One of the difficulties of conducting environmental epidemiology studies is accurate measurement of exposure. The healthy worker effect is a type of bias that says that people who have jobs tend to have higher mortality. The social environment only affects the health of people who live in developing countries. Jobs that are highly...

1-The answer is true or false a-Random errors arise from both measurement errors and sampling variation. True False b-Sampling variability stems from inaccuracies in assessing the exposure and disease occurrence. True False c-Just like bias and confounding, random errors are considered systematic errors. True False d- In addition to the p-value, the confidence interval is another method for estimating the amount of random error in epidemiological studies. True False
