- A. Sporadic disease
- B. Endemic disease
- C. Epidemic disease
- D. Pandemic disease
Explanation: An endemic disease remains continuously present at an expected level in a defined area.
Correct answer: Endemic disease- A. High sensitivity
- B. High specificity
- C. High incidence
- D. High case-fatality rate
Explanation: High specificity correctly identifies people who do not have the disease and therefore reduces false-positive results.
Correct answer: High specificity- A. Exposed people have three times the disease incidence
- B. Cases have three times the odds of past exposure
- C. The exposure causes exactly three extra cases
- D. Three percent of exposed people develop disease
Explanation: An odds ratio of 3.0 means the odds of previous exposure are three times higher among cases than controls.
Correct answer: Cases have three times the odds of past exposure- A. The association is statistically significant at 5%
- B. The relative risk is exactly 1.2
- C. The interval includes no difference between groups
- D. The exposed group has no disease cases
Explanation: For a relative risk, a value of 1 represents no difference between groups, and this interval includes 1.
Correct answer: The interval includes no difference between groups- A. Cluster sampling
- B. Systematic sampling
- C. Convenience sampling
- D. Purposive sampling
Explanation: Cluster sampling selects naturally occurring groups, such as village sections, and then studies members within the selected groups.
Correct answer: Cluster sampling- A. The spread of individual observations
- B. The expected variation of sample means
- C. The number of missing observations
- D. The percentage of diseased participants
Explanation: The standard error describes how much sample means are expected to vary from sample to sample.
Correct answer: The expected variation of sample means- A. The nurses selected the training themselves
- B. The study measured errors after training only
- C. Nurses were randomly assigned to training groups
- D. The training group was larger than the control group
Explanation: Random assignment helps balance known and unknown confounding factors between groups.
Correct answer: Nurses were randomly assigned to training groups- A. Propagated epidemic
- B. Point-source epidemic
- C. Endemic pattern
- D. Seasonal variation
Explanation: A point-source epidemic occurs when many people are exposed to a common source at one time, producing a sharp concentration of cases.
Correct answer: Point-source epidemic- A. Pie chart
- B. Scatter plot
- C. Histogram
- D. Line graph
Explanation: A pie chart shows how categories make up parts of a whole, such as immunised and unimmunised children.
Correct answer: Pie chart- A. Effect modification
- B. Random error
- C. Selection bias
- D. Recall bias
Explanation: Effect modification occurs when the strength or direction of an association differs across levels of another variable, such as sex.
Correct answer: Effect modification- A. Sporadic occurrence
- B. Endemic occurrence
- C. Epidemic occurrence
- D. Pandemic occurrence
Explanation: Sporadic disease occurs infrequently and irregularly, with isolated cases.
Correct answer: Sporadic occurrence- A. Total population
- B. Total live births
- C. Total pregnancies
- D. Total infant deaths
Explanation: Infant mortality rate uses the number of deaths among infants younger than one year divided by the number of live births in the same…
Correct answer: Total live births- A. Cancer-specific mortality rate
- B. Proportional mortality percentage
- C. Case-fatality percentage
- D. Maternal mortality ratio
Explanation: Proportional mortality percentage describes deaths from one cause as a proportion of all deaths.
Correct answer: Proportional mortality percentage- A. The most frequent observation
- B. The middle observation
- C. The average squared deviation
- D. The difference between extremes
Explanation: Variance measures the average of the squared deviations from the mean and describes dispersion.
Correct answer: The average squared deviation- A. Scatter diagram
- B. Pie chart
- C. Bar chart
- D. Frequency polygon
Explanation: A scatter diagram displays paired values for two quantitative variables and helps show their relationship.
Correct answer: Scatter diagram- A. 0.18
- B. 0.28
- C. 0.72
- D. 1.72
Explanation: The probability of an event not occurring is calculated as 1 minus the probability of its occurrence.
Correct answer: 0.28- A. Purposive sampling
- B. Simple random sampling
- C. Systematic sampling
- D. Cluster sampling
Explanation: Purposive sampling deliberately selects people who meet characteristics relevant to the research question.
Correct answer: Purposive sampling- A. Random allocation to groups
- B. Collection of data in one month
- C. Use of a large questionnaire
- D. Selection of a rural setting
Explanation: Random allocation helps balance known and unknown confounding factors between groups, strengthening the evidence that the intervention…
Correct answer: Random allocation to groups- A. The exposure occurred before illness
- B. The families live in one district
- C. The illness was recorded by nurses
- D. The participants had similar ages
Explanation: Temporality requires the suspected cause to occur before the outcome, and it is essential for a causal interpretation.
Correct answer: The exposure occurred before illness- A. Mean is greater than median
- B. Mean is less than median
- C. Mean equals the mode
- D. Median equals the range
Explanation: A long right-sided tail pulls the mean toward the high values, so the mean is greater than the median.
Correct answer: Mean is greater than median
