Analytical Methods of Healthcare Leaders (D514) – 162
Exam Questions and Verified Answers | 2026 Revision
1. What type of study uses one individual or group to gather in-depth research
in the hope of revealing universal principles?
Survey
Naturalistic Observation
Interview
Case Study
2. In a study measuring patient blood pressure, which of the following would be
considered a continuous variable?
Blood type
Systolic blood pressure readings
Patient age group
Patient gender
3. If the CFO finds a significant reduction in no-show rates after implementing
the reminder system using ANOVA, what could be a potential next step in
their analysis?
Implement another reminder system without further analysis.
Conduct a regression analysis to identify factors influencing patient
attendance.
Perform a chi-square test to compare categorical variables.
Use descriptive statistics to summarize patient demographics.
,4. If a healthcare provider uses predictive analytics to identify at-risk patients,
what might be a direct outcome of this application?
Reduced patient engagement in treatment plans
Improved early intervention strategies for high-risk patients
Increased administrative costs due to data analysis
Standardized treatment for all patients regardless of risk
5. Describe how regression analysis can be utilized in evaluating the impact of
supervisor attitudes on patient rehabilitation outcomes.
Regression analysis focuses solely on descriptive statistics without any
predictive capabilities.
Regression analysis is used to compare means between groups
without considering relationships.
Regression analysis is primarily used for ethical considerations in
research.
Regression analysis can quantify the relationship between
supervisor attitudes and patient rehabilitation outcomes, allowing
for predictions and insights into how changes in attitudes may affect
outcomes.
6. The ethical principal of beneficence states that one has an obligation to
________.
conduct the research within the budget
provide detailed information on the research findings
conduct the research in a timely manner
remove all identifying information from the survey or questionnaire
, remove existing harms, to confer benefits, and to minimize risks
wherever and whenever possible
7. Describe the significance of standard deviation in interpreting healthcare
data.
Standard deviation measures the central tendency of the data.
Standard deviation indicates how much individual data points
deviate from the mean, helping to understand the spread of patient
outcomes.
Standard deviation is used to calculate the correlation between
variables.
Standard deviation provides the total number of observations in the
dataset.
8. In a study comparing the effectiveness of three different diets on weight loss,
which statistical method would you use to analyze the results, and why?
ANOVA, because it allows for comparison of the means of more
than two groups.
Descriptive statistics, because it summarizes the data without testing
differences.
T-test, because it compares two groups at a time.
Regression analysis, because it predicts weight loss based on diet
type.
9. Describe how nominal data differs from ordinal data in terms of
measurement.
Nominal data can be measured on a scale, whereas ordinal data
cannot.
, Nominal data is always discrete, while ordinal data can be continuous.
Nominal data represents categories without a specific order, while
ordinal data has a defined order among categories.
Nominal data is numerical, while ordinal data is purely qualitative.
10. Describe the relationship between independent and dependent variables in
a research study.
The dependent variable influences the independent variable's
outcome.
The independent variable is manipulated to observe its effect on
the dependent variable, which is measured.
Both variables are independent of each other and do not affect the
results.
The independent variable is always a constant in research studies.
11. How does the principle of autonomy impact the ethical considerations in
healthcare research?
The principle of autonomy requires researchers to prioritize the needs
of the healthcare system over individual rights.
The principle of autonomy suggests that researchers should avoid
discussing risks with participants.
The principle of autonomy impacts ethical considerations by
ensuring that participants are fully informed and can voluntarily
consent to their involvement.
The principle of autonomy allows researchers to make decisions on
behalf of participants without their consent.
