,1. Which of the following statistical tests would
be most appropriate to compare the mean blood
pressure levels of patients before and after a new
medication intervention?
A) Independent samples t-test
B) Paired samples t-test
C) Chi-square test
D) Analysis of Variance (ANOVA)
Answer: B) Paired samples t-test
Rationale: A paired samples t-test is used when
comparing the means of two related groups, such
as before and after measurements within the same
group.
2. In a study examining the relationship between
smoking status and lung cancer incidence, which
statistical analysis would be most appropriate?
A) Pearson correlation
B) Linear regression
C) Chi-square test
D) Independent samples t-test
Answer: C) Chi-square test
Rationale: A chi-square test is used to assess the
association between two categorical variables,
such as smoking status and lung cancer incidence.
3. A researcher is interested in determining if there
is a difference in pain scores among patients
, receiving three different types of pain medication.
Which statistical test should be used?
A) Analysis of Variance (ANOVA)
B) Kruskal-Wallis test
C) Mann-Whitney U test
D) Independent samples t-test
Answer: A) Analysis of Variance (ANOVA)
Rationale: ANOVA is used to compare the means
of three or more groups, making it suitable for
comparing pain scores among multiple medication
groups.
4. Which of the following measures is most
appropriate for describing the central tendency of
a skewed distribution of patient ages in a
healthcare setting?
A) Mean
B) Median
C) Mode
D) Range
Answer: B) Median
Rationale: The median is the preferred measure of
central tendency for skewed distributions, as it is
less affected by extreme values compared to the
mean.
5. A nurse researcher is interested in determining
if there is a relationship between nurse-patient
communication scores and patient satisfaction
