Quantitative Research Methods Evaluation

This assignment evaluates quantitative research methods used in four peer-reviewed thesis studies related to quality improvement in public healthcare settings. The studies employed mixed-methods or qualitative approaches, including face-to-face interviews, online surveys, and systematic observations. The evaluation assesses the correctness of the sample population, discusses the statistical methods used, and compares the results, applications, and conclusions among the four studies.

Introduction
After overviewing the entire topic some of the search engines such as Google Scholar
will be used for gathering at least 4 contemporary peer-reviewed articles of thesis research
studies that are mixed-methods or qualitative nature as suggested in the assignment.
Furthermore, the articles will be completely related to the quality improvement in the public
healthcare settings. Firstly, the study will highlight the phenomenon of interest and summarize
the entire study. Secondly, the study will also discuss whether the population and sample that
was used for the study were correct or not. Lastly, applications, limitations, conclusion, and
results will be summarized. However, a comparison will also be provided between the
conclusions, results, and application of the four studies that are selected with regards to a
summary paragraph. Additionally, the entire study will be accompanied by the PowerPoint
presentation.
Discussion
The type of study
Four articles have been taken into account for performing the entire study with regards to
the quantitative methods used in these studies. Quantitative research is a method where the
measurable data is used for formulating some facts and uncovering patterns with regards to the
research. However, the quantitative method that is used for the 4 studies mainly includes face to
face interviews, online surveys, telephone interviews, systematic observations and the online

polls. It can be also said that the quantitative methods are largely used in the healthcare settings
because the data collection method in the quantitative method is much more structured than the
qualitative methods (Stellefson, Dipnarine, and Stopka, 2013).
Sample population used correctly or not
The sample population that was used in the four studies was correct. It was observed that
the studies combined the sampling strategies as it is correct for aiming the implementation
research and more consistent with the current developments with regards to the quantitative
methods (Ozcan, 2014). Different type of people was chosen for conducting the studies. In one
of the study, it has been observed that the sampling according to the age group made it quite
easier for the researchers to understand which age group has diabetes and chronic disease the
most.
Comparing results, applications, and conclusions among the four studies
The results were quite different in the four studies even after using the same method
namely the quantitative method. In one of the research, it has been observed that the order-entry
system results decreased the costs of the pharmacy when it was introduced. In another research
result, it has been witnessed that the Chronic Care Model is one of the most effective methods
for managing diabetes when it was surveyed among the different age group of people (Brett and
et al, 2014). Throwing light on the above-mentioned statement it can be said that both of the
results are quite different.

Statistical method used in the studies
The statistical methods that are used in the studies are as follows: The One-Group
Pretest-Posttest Design, The One-Group Posttest-Only Design, The One-Group Pretest-Posttest
Design Using a Nonequivalent Dependent Variable, The One-Group Pretest-Posttest Design
Using a Double Pretest, The Repeated-Treatment Design, and The Removed-Treatment Design.
However, the statistical designs used in the studies play an important role in getting approximate
results where the solutions that are deterministic are quite hard to apply (Clement and et al,
2015).
