QUESTIONS AND CORRECT ANSWERS
Quantitative Research - CORRECT ANSWER Involves the analysis of numeric data,
employing statistical methods to draw conclusions and make inferences. This type of research focuses
on variables and aims to measure and quantify relationships between variables, providing numerical
insights.
Example of Quantitative Research - CORRECT ANSWER Studying the efficacy and safety of
a specific medication in treating a particular medical condition compared to other treatments or
placebo.
Example of Quantitative Research - CORRECT ANSWER Investigating the correlation
between specific genetic markers and the risk of developing certain diseases or conditions, such as the
BRCA gene and breast cancer risk.
Example of Quantitative Research - CORRECT ANSWER Analyzing the cost-effectiveness of
a particular medical intervention or treatment, such as a new drug or surgical procedure.
Example of Quantitative Research - CORRECT ANSWER Assessing the impact of a specific
public health intervention, such as a vaccination program, on disease incidence and prevalence.
Key Characteristics of Quantitative Research - CORRECT ANSWER Numeric - measurable,
graphs, tables, etc.
Key Characteristics of Quantitative Research - CORRECT ANSWER Verifiable, accurate -
value of the data is in the number.
Key Characteristics of Quantitative Research - CORRECT ANSWER Examples are sample
size (n), mean, median, mode, range, standard deviation.
Qualitative Research - CORRECT ANSWER Involves the analysis of non-numeric data,
describing observations, experiences, or phenomena. Qualitative research relies on methods such as
interviews, observations, or content analysis to gather and interpret subjective information. The data is
, often categorized before summarizing, allowing for a deeper understanding of complex and context-
specific phenomena.

disorders.
Qualitative Research: Examples related to healthcare disparities - CORRECT ANSWER
Investigate disparities in healthcare access, utilization, and outcomes among different
population groups, such as racial or ethnic minorities, socioeconomically disadvantaged individuals,
or rural communities.
Qualitative Research: Examples related to healthcare quality assessment - CORRECT ANSWER
Study assesses the quality of healthcare services from the perspective of patients, caregivers, or
healthcare providers.
Qualitative Research: Examples related to healthcare interventions - CORRECT ANSWER
Evaluate the implementation and effectiveness of healthcare interventions, such as new
treatments, programs, or policies.
Qualitative Research: Examples related to end-of-life care - CORRECT ANSWER Explore the
experiences and preferences of patients, families, and healthcare providers regarding end-of-life care
and decision-making.
Qualitative Research: Examples related to health behaviors - CORRECT ANSWER Investigate
factors influencing health behaviors, such as diet, exercise, smoking, or medication adherence.
Nominal Variable - CORRECT ANSWER Involves names or categories. Examples includes
various cancer types, different insurance companies, specialties offered
Ordinal Variable - CORRECT ANSWER Involves order of a category. For example, a pain
scale, a stage of cancer, a trimester of pregnancy
Ordinal Variable - CORRECT ANSWER Type of variable where the order or ranking of values
matters, but the differences between values may not be uniform. In these, the intervals between values
