This epidemiology quiz helps you practice core measures like relative risk and ASHD rates and see where you might need review. Use it to prep for class or exams, spot gaps fast, and build confidence. Warm up with these sample questions, then try the full quiz .
Study Outcomes
- Understand ASHD rates -
Calculate and interpret incidence and prevalence measures of arteriosclerotic heart disease to differentiate between rate-based and proportion-based metrics.
- Calculate relative risk -
Use data from cohort scenarios to compute relative risk values and assess the strength of associations between exposures and health outcomes.
- Compute odds ratios -
Derive and interpret odds ratios from case - control data sets to quantify the relationship between exposures and diseases.
- Identify epi quiz concepts -
Recognize and explain fundamental epidemiologic principles presented in the epi.tests quiz to enhance comprehension and retention.
- Differentiate study measures -
Compare and contrast relative risk, odds ratios, and ASHD rates to determine the appropriate application of each measure in epidemiologic studies.
- Apply teacher epi assessment sample questions -
Engage with teacher epi assessment sample questions to simulate real-world testing scenarios and reinforce core epidemiology skills.
Cheat Sheet
- Relative Risk (RR) Calculation -
Use the cohort formula RR = [a/(a+b)] ÷ [c/(c+d)] to compare incidence in exposed versus unexposed groups. For example, if 30 of 100 exposed and 10 of 100 unexposed develop the disease, RR = 0.3/0.1 = 3.0, indicating a threefold higher risk (CDC, 2022).
- Odds Ratio (OR) Interpretation -
In case - control studies, compute OR = (a×d) ÷ (b×c) from a 2×2 table to estimate exposure odds among cases versus controls. An OR >1 suggests a positive association; for instance, OR = 2.5 means cases had 2.5 times the odds of exposure (J Epidemiol Res).
- Age-Standardized Heart Disease Rate (ASHD) -
Apply the direct standardization method by weighting age-specific ASHD rates against a standard population (e.g., WHO world standard) to remove age-structure bias. This lets you compare regions fairly - simply multiply each age-specific rate by its standard population weight and sum the results (WHO, 2021).
- Sensitivity & Specificity -
Recall Sensitivity = TP/(TP+FN) and Specificity = TN/(TN+FP), where TP/FN are true/false negatives. Use the mnemonics "SnOUT" (high Sensitivity rules OUT disease) and "SpIN" (high Specificity rules IN disease) for quick recall (Johns Hopkins Univ.).
- Maximizing epi.tests Practice -
Leverage epi.tests quizzes and teacher epi assessment sample questions to identify epi quiz gaps by grouping flashcards on RR, OR, AR and study design. Pro tip: use the "FACES" mnemonic - Flashcards, Assess, Chart, Explain, Self-test - to boost retention and confidence before any epi quiz.
