SPHHS 150 Final Exam UPDATED
ACTUAL QUESTIONS AND CORRECT
ANSWERS
Key Statistical Concepts - CORRECT ANSWER Measurements like incidence-,
prevalence-, rates, and risk that help describe disease patterns and evaluate interventions in
public health.
Importance of Statistical Concepts - CORRECT ANSWER They guide research,
identify trends, evaluate programs, and ensure decisions are based on objective evidence.
Public Health Data Sources - CORRECT ANSWER Surveillance systems; surveys;
registries; medical records; census data.
Strengths & Limitations of Data Sources - CORRECT ANSWER Surveillance =
timely; surveys = detailed but expensive; registries = accurate but narrow; medical records =
detailed but inconsistent.
Data-Driven Decision Making - CORRECT ANSWER Using numerical evidence to
guide public health policy and practice for accuracy and effectiveness.
Best Practices in Data Visualization - CORRECT ANSWER Use clear simple graphs,
avoid clutter, highlight key trends, ensure visual accuracy.
PERIE Framework - CORRECT ANSWER Problem; Etiology; Recommendations;
Implementation; Evaluation.
PERIE Step 1 - Problem - CORRECT ANSWER Identify who is affected, what the
condition is, and when/where it occurs.
, PERIE Step 2 - Etiology - CORRECT ANSWER Determine the causes and risk factors
of the health issue.
Evidence-Based Intervention - CORRECT ANSWER A program or policy supported
by strong scientific research and proven effectiveness.
Types of Evidence in Public Health - CORRECT ANSWER Epidemiological data;
randomized trials; observational studies; qualitative data.
Why Evidence-Based Programs - CORRECT ANSWER Ensures effectiveness, avoids
harm, and uses resources efficiently.
Definition of Epidemiology - CORRECT ANSWER Study of the distribution and
determinants of disease in populations.
What Epidemiologists Do - CORRECT ANSWER Assess population health,
investigate causes, respond to outbreaks, evaluate interventions.
Incidence - CORRECT ANSWER Number of new cases of a disease over a period of
time.
Prevalence - CORRECT ANSWER Total number of existing cases at a given time.
Outbreak - CORRECT ANSWER Localized increase in disease cases.
Endemic - CORRECT ANSWER Disease that is regularly found at expected levels in a
population.
Epidemic - CORRECT ANSWER Cases occur above the expected level in a
population.
