Correct answer
Question 1
10 / 10 pts
Which of the following best describes qualitative research?
None of the above.
Research that involves collecting and analyzing both numerical and non-numerical data.
Research that involves collecting and analyzing numerical data.
Research that involves collecting and analyzing non-numerical data.
Correct! Qualitative research involves collecting and analyzing non-numerical data. This can include words (through interviews and focus groups), images, or objects to describe experiences, perceptions, and perceptions, which are inherently subjective and rich in context.
Correct answer
Question 2
10 / 10 pts
Which of the following is an example of secondary data?
Data collected through surveys.
Data collected through interviews.
Data obtained from hospital records.
Correct! Data obtained from hospital records is an example of secondary data – existing data that initially was gathered by another entity (e.g., the hospital) and then later obtained for another purpose.
Data collected through experiments.
Correct answer
Question 3
10 / 10 pts
Which type of study is primarily concerned with providing a detailed account of a particular subject without attempting to test a hypothesis?
Observational study.
Experimental study.
Analytic study.
Descriptive study.
Correct! Descriptive studies are used to identify patterns or trends over time and can provide important information about the who, what, when, and where of health-related events. Descriptive studies do not attempt to test hypotheses.
Correct answer
Question 4
10 / 10 pts
What is a cohort in epidemiology?
A group of people with a specific disease.
A group of people from a specific geographic area.
A group of people who are part of a randomized controlled trial.
A group of people with a common characteristic or set of characteristics.
Correct! In epidemiology, a cohort refers to a group of people that share a common characteristic or a set of characteristics.
Correct answer
Question 5
10 / 10 pts
What is the main purpose of a case-control study?
To determine the prevalence of a disease.
To determine the incidence of a disease.
To test the effectiveness of a treatment.
To identify risk factors associated with a disease.
Correct! The main purpose of a case-control study is to identify individuals who have a particular condition or disease (e.g., cases), and then select or identify a comparison, or control group of people do not have the condition or disease (e.g., controls). Researchers then compare the two groups (cases and controls) to understand what risk factors might be associated with the condition or disease in the ”case” group.
Correct answer
Question 6
10 / 10 pts
Which type of study design allows for the determination of causality?
Cohort study.
Randomized controlled trial.
Correct! Randomized controlled trials or RCTs which are experimental studies allow for the determination of causality. These are often considered as the gold-standard of study types. Cross-sectional, case-control and cohort studies are observational studies.
Case-control study.
Cross-sectional study.
Correct answer
Question 7
10 / 10 pts
In a research study, why is it often necessary to use a sample instead of the entire population?
Because it is often impractical or impossible to study the entire population.
Correct! Samples are often used in research as opposed to an entire population because it is often impractical or impossible to study the entire population. Studying an entire population can be time-consuming and costly.
Because it is more accurate to use a sample.
Because using a sample eliminates all potential bias.
Because the population is always unknown.
Correct answer
Question 8
10 / 10 pts
Which type of statistics uses sample data to make predictions or draw conclusions about a population?
Both descriptive and inferential statistics
Neither descriptive nor inferential statistics
Inferential statistics
Correct! Inferential statistics use sample data to make predictions or draw conclusions about a population.
Descriptive statistics
Correct answer
Question 9
10 / 10 pts
Which of the following best describes the purpose of epidemiology in public health?
To design and analyze medical experiments.
To evaluate the effectiveness of a health education curriculum on student’s intention to engage in risky behaviors.
To study the distribution, pattern, and determinants of health-related states or events in specified populations, and the application of this study to control health problems.
Correct! Epidemiology is one of the core sciences of public health which is focused on the distribution, pattern, and determinants of health-related states or events in specified populations, and the application of this study to control health problems.
To apply statistical procedures to understand and describe health phenomena.
Correct answer
Question 10
10 / 10 pts
Which of the following is an applied example of epidemiology in practice?
Designing a new data collection tool for a research study.
Analyzing the results of a clinical trial for a new drug.
Conducting a cross-sectional survey to understand the prevalence of a disease in a population.
Correct! An applied example of epidemiology in practice is conducting a cross-sectional survey to understand the prevalence of a disease in a population.
Using statistical models such as logistic regression to predict future disease likelihood.
