D514 Analytical Methods of Healthcare
Leaders Exam Questions & Answers
(Grade A+)
ANOVA test -
correct answer ✅Analysis of variance (ANOVA) may be used in
research studies where there are two or more groups to compare.
Chi-square tests -
correct answer ✅Chi-square tests determine if an association
exists between two categorical variables.
Control group -
correct answer ✅In a healthcare environment, this group of
patients does not receive the treatment that is being studied.
Experimental group -
correct answer ✅This group of patients receives the treatment
being studied with follow-up observation to determine the effect of
the treatment.
F-test -
correct answer ✅The F-test is designed to test if two population
variances are equal. The ratio of the two variances is compared. If
they are equal, the ratio of the variances will be 1.

Leaders Exam Questions & Answers
(Grade A+)
Frequency -
correct answer ✅Frequencies measure how often a particular
value occurs to assess the importance of a value or check the
variation of the values in a study.
Hypothesis -
correct answer ✅A proposed explanation for an observation that
leads to a prediction. Through investigation and the use of
statistical data, those doing the study will either confirm or reject
the hypothesis. Testing the hypothesis will show if there is a link (or
not) between two or more variables.
Integrity -
correct answer ✅Research always makes some assumptions,
depending on the type of method used. Research assumptions
must be identified to determine possible breaches of integrity.
Interval data -
correct answer ✅Interval data includes units of equal size, such as
IQ results. There is no zero point. An example of interval scale is

(Grade A+)
time: Time is measured in 24 hours in each day; the time between
each hour is the same, 60 minutes.
Mean -
correct answer ✅Mean is the arithmetic average. Divide the sum
of all scores by the total number of scores.
Median -
correct answer ✅Median is the midpoint of the distribution of
values, or the point above or below which 50 percent of the values
fall.
Methods section components -
correct answer ✅When analyzing the quality of a study, a careful
evaluation of the research methods can reveal critical details about
population and sample, covariables and hypothesis, data
presentation, statistical analysis, and study limitations.
Misleading statistics -
correct answer ✅Interpreting and presenting the results of data
analysis affords many opportunities for accidental or deliberate
misrepresentations of data. Common examples include implying

causation, extrapolating beyond the reasonable, relying on a biased
or incomplete sample, and using inappropriate graphical
representations.
Mode -
correct answer ✅Mode is the value that occurs most frequently in
the data.
Multivariate regression analyses -
correct answer ✅Multivariate regression analyses can be used to
analyze and adjust risk. This analysis model contrasts each
measured factor to the patient's risk of a particular outcome.
Nominal data -
correct answer ✅Nominal data can be measured as a frequency or
percentage, and the mean of these data cannot be calculated.
Nominal data in healthcare might include demographic information
about patients. The word nominal means "pertaining to a name."
Ordinal data -
correct answer ✅Ordinal data can be measured as a frequency,
and the mean of ordinal data is often calculated. Ordinal data in
