AND ANSWERS SET A+
✔✔ Quantitative Research - ✔✔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 - ✔✔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 - ✔✔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 - ✔✔Analyzing the cost-effectiveness of a
particular medical intervention or treatment, such as a new drug or surgical procedure.
✔✔Example of Quantitative Research - ✔✔Assessing the impact of a specific public
health intervention, such as a vaccination program, on disease incidence and
prevalence.
✔✔Key Characteristics of Quantitative Research - ✔✔Numeric - measurable, graphs,
tables, etc.
✔✔Key Characteristics of Quantitative Research - ✔✔Verifiable, accurate - value of the
data is in the number.
✔✔Key Characteristics of Quantitative Research - ✔✔Examples are sample size (n),
mean, median, mode, range, standard deviation.
, ✔✔Qualitative Research - ✔✔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.
✔✔Qualitative Research: Examples related to chronic illnesses - ✔✔The experiences of
patients living with chronic illnesses, such as cancer, diabetes, or mental health
disorders.
✔✔Qualitative Research: Examples related to healthcare disparities - ✔✔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 -
✔✔Study assesses the quality of healthcare services from the perspective of patients,
caregivers, or healthcare providers.
✔✔Qualitative Research: Examples related to healthcare interventions - ✔✔Evaluate
the implementation and effectiveness of healthcare interventions, such as new
treatments, programs, or policies.
✔✔Qualitative Research: Examples related to end-of-life care - ✔✔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 - ✔✔Investigate factors
influencing health behaviors, such as diet, exercise, smoking, or medication adherence.
✔✔Nominal Variable - ✔✔Involves names or categories. Examples includes various
cancer types, different insurance companies, specialties offered
✔✔Ordinal Variable - ✔✔Involves order of a category. For example, a pain scale, a
stage of cancer, a trimester of pregnancy
✔✔Ordinal Variable - ✔✔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 are not consistent. An example is a pain scale where the order of pain severity
matters, but the difference between a rank of "7" and "5" may not be the same as
between "5" and "3".
✔✔Interval Variable - ✔✔Difference between two values or numbers. For example,
body temperature, height, weight, age etc
