1.
The number of nursing
students enrolled in a particular nursing program between the years of 2010 and
2016, respectively, were 563, 593, 606, 520, 563, 610, and 577. Determine the
mean (), median (MD), and mode of the number of
the nursing students enrolled in this program. Show your calculations.
2. What is the mode for the variable inpatient
complications inTable 2 of the Winkler et al. (2014) study?
What percentage of the study participants had this complication?
3. Does the distribution of inpatient complications
have a single mode, or is this distribution bimodal or multimodal? Provide a
rationale for your answer.
.
4. As reported inTable 1, what are the three most common cardiovascular
medical history events in this study, and why is it clinically important to
know the frequency of these events?
5. What are the mean and median lengths of stay
(LOS) for the study participants?
.
6. Are the mean and median for LOS similar or
different? What might this indicate about the distribution of the sample?
Provide a rationale for your answer.
7. Examine the study results and determine the mode
for arrhythmias experienced by the participants. What was the second most
common arrhythmia in this sample?
8. Was the most common arrhythmia in Question 7
related to LOS? Was this result statistically significant? Provide a rationale
for your answer.
9. What study variables were independently
predictive of the 50 premature ventricular contractions (PVCs) per hour in this
study?
10. InTable 1, what race is the mode for this sample? Should
these study findings be generalized to American Indians with ACS? Provide a
rationale for your answer.

What were the name and
type of measurement method used to measure Caring Practices in the Roch, Dubois, and
Clarke (2014) study?
2.
The data collected with
the scale identified in Questions 1 were at what level of measurement? Provide
a rationale for your answer.
3.
What were the subscales
included in the CNPISS used to measure RNs’ perceptions of their Caring
Practices? Do these subscales seem relevant? Document your answer.
4. Which subscale for Caring Practices had
the lowest mean? What does this result indicate?
5. What were the dispersion results for the
Relational Care subscale of the Caring Practices inTable 2? What do these results indicate?
6. Which subscale of Caring Practices has the
lowest dispersion or variation of scores? Provide a rationale for your answer.
7. Which subscale of Caring Practices had the
highest mean? What do these results indicate?
8. Compare the Overall rating for Organizational
Climate with the Overall rating of Caring Practices. What do these results
indicate?
9. The response rate for the survey in this study
was 45%. Is this a study strength or limitation? Provide a rationale for your
answer.

10 Questions to Be Graded
1.
What demographic
variables were measured at the nominal level of measurement in theOh et al. (2014) study? Provide a rationale for your
answer.
2. What statistics were calculated to describe body
mass index (BMI) in this study? Were these appropriate? Provide a rationale for
your answer.
3.
Were the distributions
of scores for BMI similar for the intervention and control groups? Provide a
rationale for your answer.
4.
Was there a
significant difference in BMI between the intervention and control groups?
Provide a rationale for your answer.
5.
Based on the sample size
of N = 41, what frequency and percentage of the sample smoked?
What frequency and percentage of the sample were non-drinkers (alcohol)? Show
your calculations and round to the nearest whole percent.
6.
What measurement method
was used to measure the bone mineral density (BMD) for the study participants?
Discuss the quality of this measurement method and document your response.
7.
What statistic was
calculated to determine differences between the intervention and control groups
for the lumbar and femur neck BMDs? Were the groups significantly different for
BMDs?
8.
The researchers stated that
there were no significant differences in the baseline characteristics of the
intervention and control groups (seeTable 2). Are these groups heterogeneous or homogeneous
at the beginning of the study? Why is this important in testing the
effectiveness of the therapeutic lifestyle modification (TLM) program?
9.
Oh et al. (2014, p. 296) stated that “the adherence rate to the
TLM program was 99.6%.” Discuss the importance of intervention adherence, and
document your response.
10. Was the sample for this study adequately
described? Provide a rationale for your answer.
