NURS 3151 / NURS 3150 WEEK 3: Quantitative Research Designs and Methods
NURS 3151 / NURS 3150 WEEK 3: AT A GLANCE
QUANTITATIVE RESEARCH DESIGNS AND METHODS
INTRODUCTION
Andre is a nursing student who has just completed the first 2 weeks in a nursing research course. He has defined a clinical research question for his health care setting and has also determined that the research problem exists in the literature. However, his approach to defining a solution for his research question requires that he receive approval from his health care setting before testing it.
However, Andre is not quite sure what he needs to do next. Eager to start, Andre jumps ahead in the course syllabus and sees that in the following weeks he will read about quantitative research design and methods. Slightly confused, he is not quite sure what is meant by quantitative research design and methods and begins drafting an email message to his instructor to see if he might be able to use this information for testing his research question in practice.
What is quantitative research design? What different methods might exist for engaging in quantitative research for nursing practice?
As you have explored in this course, your next step in the research process is to determine what type of research design and methods you will use to engage in research for your research question. While it is possible that many research designs and methods might be appropriate for your particular research question, gaining a firm understanding of different research designs and methods is another useful skill for engaging in nursing research and practice.

This week, you explore the different categories of quantitative research designs used in a clinical research studies. These include experimental, quasi-experimental, descriptive and correlational designs. You will examine the basic characteristics of each design (e.g., causality, control, bias, validity, randomization, probability). You will also examine the basic features of the methods used to conduct most quantitative research designs, such as sample selection, data collection and measurement of variables, as well as data management and analyses.
LEARNING OBJECTIVES
Students will:
- Demonstrate an understanding of the basic characteristics of quantitative research designs
- Analyze the strengths and weaknesses of methods used in quantitative research designs

NURS 3151 / NURS 3150 WEEK 3 DISCUSSION:
RELIABILITY AND VALIDITY OF RESEARCH METHODOLOGY
Selection of the appropriate sample is critical to the reliability and validity of research methodology. The sample must be representative of the population that is being studied. Researchers often report both the inclusion and exclusion criteria for the sample. There are many different methods for selecting a sample and random sampling provides the high control of outside variables but is often difficult to utilize in many studies.
For this Discussion, please review the following:
- For this assignment, read the article by Zaccari, Callahan, Storzback, & McFarlane (2020), listed in the resource section for this week.
BY DAY 3
Prepare at least a 350-word post discussing the strengths and weaknesses of the sampling method used in this study and if the sampling method promoted reliable and valid results. Include in the discussion if there is anything the researcher could have done to improve the sampling process.
Note: Post a 3-paragraph (at least 350 words) response. Be sure to use evidence,in-text citations, and essay-level writing skills, including the use of transitional materialand organizational frames. Use the writing resources and the Discussion Rubric to develop your post.
BY DAY 7
Read two or more of your colleagues’ postings from the Discussion question.
Respond to two or more of your colleagues with a comment that asks for clarification, provides support for, or contributes additional information.
Post a Discussion entry on 3 different days of the week. See the Discussion Rubrics for more information.

NURS 3151 / NURS 3150 WEEK 3 ASSIGNMENT:
METHODS USED IN QUANTITATIVE RESEARCH
As you have explored this week, there are various methods a researcher may use to engage in quantitative research design. While the methods presented this week are not exhaustive, they do introduce numerous features that you will likely encounter when reviewing, accessing, and researching the nursing practice literature. Whether you are creating new research or searching the literature to add support for a research question you are interested in, understanding the quantitative research designs that may be used for nursing practice will likely inform how you will conduct research for your health care setting. As you continue to build upon your research skills as a nursing researcher and professional, understanding how to engage in quantitative research design is a valuable asset.
For this Assignment, view this week’s Quantitative Research Designs PowerPoint webinar and pay close attention to its content on the basic elements of research methods (e.g., sample, data collection, measurement, analysis). Then, be sure to review the research study by Latour, O’Byrne, McCarthy, Chacko, Russell, & Price (2020), included in this week’s resources.
Note: While not a required resource, you might find the definitions in the Encyclopedia of Nursing Research helpful for this assignment.
This assignment involves identifying and describing the strengths and weaknesses of the research method used in the Latour, O’Byrne, McCarthy, Chacko, Russell, & Price (2020) research article in this week’s resources.
- Focus on the research design, sample data collection methods, tools used for data collection, and the plan for data analysis as discussed in the Latour, O’Byrne, McCarthy, Chacko, Russell, & Price (2020) article.
- Identify at least two strengths and two weaknesses of the study based on reliability and validity by including additional support with citations from resources not assigned this week.
- Use the copy of the Journal Club Template for Quantitative Research located in this week’s resources. The template includes an area for each element discussed in the study. Note: Assignments will not be accepted unless the required template is used.
- Be brief, paraphrase and summarize each of the elements clearly on the form.
- Provide the full citation of the article used for this Assignment on the template.
BY DAY 7
Once this is complete, save your file and submit the Journal Club Template for Quantitative Research to the submission link. Note that the template provided must be used.
