HOSA EPIDEMIOLOGY PRACTICE EXAM
BANK 2026 TESTED QUESTIONS AND
ANSWERS GRADED A+
⩥ Epidemic. Answer: a health problem that exists in a community to a
greater degree than you would expect.
⩥ Bias. Answer: a flaw in either the study design or data analysis that
leads to an erroneous result.
⩥ Case Fatality rate. Answer: mathematical quantity that describes the
severity of a disease Y, proportion of persons diagnosed with a disease Y
who actually die from disease Y during the period of observation:
⩥ exposure. Answer: generic term used to describe the effective
presence of any agent or factor that is thought to cause disease
⩥ Hypothesis testing. Answer: The epidemiological process by which
researchers ask the question: " Does the association that I have observed
represent a causal relationship between the putative exposure and the
disease?"
⩥ Prevalence. Answer: mathematical quantity that describes the
presence of a disease Y in a population
, # with disease Y in population p at a given time
# in population p
⩥ Incidence. Answer: the occurrence of a disease Y in a population. It is
the proportion of persons in the population who newly develop the
disease Y within a given time period (t)
# who develop the disease Y in population p in a time t
# in population p
⩥ Racial and ethnic health disparities. Answer: There are very few
diseases for which those differences result from biological factors others
can usually be traced to socioeconomic phenomena
⩥ Attributable risks. Answer: group of measures which describe the
amount of disease risk that can be attributed to a given factor X
(Incidence in population) - (Incidence in unexposed group)]/ (Incidence
in population)
⩥ Screening. Answer: process of early diagnosis of a disease, i.e.
identification of disease or risk factors for the disease in its pre-
symptomatic or pre-clinical stage. Breast cancer screening
⩥ Passive Surveillance. Answer: more common form of surveillance
used by most local and state health departments; health care providers
report notifiable conditions
