Step by step
Solved in 2 steps
- Please answer ASAP 12. Which of the following statement is false regarding a cross-sectional study? a. Prevalence of a variable can be estimated.b. It cannot determine causality between the exposure and the outcome.c. There may be a comparison group in the design of the study.d. Relative risk can be calculated as a measure of association.e. One of its advantages is there cannot be any lost to follow-upIn a cohort study, the ratio of the incidence rate of a disease in an exposed group to the incidence rate of the disease in a nonexposed group is the: a. Relative risk b. Risk difference c. Prevalence ratio d. Odds ratioWhich of the following is best at showing the life expectancy of an individual within a population? quadrat mark and recapture survivorship curve life table
- Studies of populations in which observation is accompanied by experimental manipulation of some population members are referred to as a. case studies b. intervention studies c. laboratory studies d. epidemiological studies8. True or False? Relative risk is an ideal form of measurement for a retrospective cohort study design because it allows researchers to recruit both individuals with the outcome of interest and individuals without the outcome of interest, then match individuals from each of the respective groups to individuals of the other group to determine if a specific exposure caused the outcome of interest.Which prioritization criterion should be given the most emphasis if you want to analyze the probability of minimizing or eradicating the family's health problem? A. Modifiability B. Nature of the Problem C. Preventive Potential D. Salience
- Should population health management focus on populations with the greatest disparities and health inequity or areas where the greatest financial opportunities are present? why.In which scenario would it be best to select a case-control study design over a retrospective cohort study design? (select one best answer) Group of answer choices a. The outcome being studied is rare b. The exposure of interest is rare c. There are multiple outcomes of interest d. When were are interested in directly calculating incidence rates e. None of the aboveWhich of the following is not true of cohort studies? a. Risk can be observed directly in a cohort study b. Cohort studies are good for studying the impact of rare exposures in the population c. The exposure is well defined in cohort studies d. Cohort studies carry the highest risk of misclassification of exposures (that is, incorrect identification of participants as exposed or unexposed)
