NURS 8200/NURS 8200F/NURS 8200M/NURS 8200C/NURS 8200A: Research Methods for Evidence-Based Practice | Week 3

How is quantitative research conducted? What issues are important for researchers to keep in mind as they conduct a study? One of the most important considerations in quantitative research is how to select an appropriate subset, or sample, of a population to study, so that inferences using the data can be made about the overall population. The measurement process is also critical, as researchers must determine how to describe and measure concepts in ways that produce valid and reliable results. As a health care professional, it is vital that you understand how these key issues affect the collection of data that may be used to inform evidence-based practice.

This week focuses on sampling methods and data collection, two critical components of the research process. You continue to develop your article critique by evaluating the sampling and data collection methods used in your selected study.

Learning Objectives

Students will:

• Describe the target population and sampling strategy using the research question identified in Week 2>
• Formulate an appropriate approach for collecting data from a selected sample

• • Chapter 15, “Sampling”Chapter 15 introduces key concepts and components of sampling theory and the sampling process. The chapter discusses several important sampling considerations, including target population, hypothetical population, accessible population, elements, subjects, participants, and generalizability of research findings based on sampling methods.

 

• Chapter 20, “Collecting and Managing Data”Chapter 20 explains how data collection is an integral part of research and presents methods for collecting and managing data.

This article discusses a mixed-method study of the work opportunities for people with behaviorally driven health conditions such as HIV/AIDS and drug and alcohol abuse. The article describes the results of qualitative interviews and quantitative surveys of employers in China and the United States in an effort to analyze employer perspectives, stigma, and the possibility for stigma change.

This article describes a quantitative research study on the amount of time nurses spend on direct patient care in a neuro-rehabilitation setting. The article offers suggestions for future studies that focus on work sampling and discusses how staffing requirement estimates should consider indirect care and non-patient activities in addition to direct patient care needs.

Discussion: Sampling

The temptation to form premature theories upon insufficient data is the bane of our profession.

—Sherlock Holmes (from The Valley of Fear, by Sir Arthur Conan Doyle)

Sherlock Holmes, the great fictional logician, may have made this reprimand in reference to the science of criminal investigation, but the underlying principle holds true for all branches of research. Now that you have identified a research problem and developed hypotheses, the next step is to identify your sample and begin gathering data that will answer your research questions. The process of sampling to gather data is a crucial step in the research process in that you must be sure that the instruments and sample population mesh well with the study’s goals and objectives so that they will produce valid and reliable results.

For this Discussion, you identify a target population and sample appropriate for addressing the research problem you formulated in the Week 2 Discussion.

To prepare:

• Review this week’s media presentation and consider Dr. Pothoff’s comments on sampling.
• Recall the research problem, question, and hypothesis you developed in Week 2’s Discussion. With this in mind, ask yourself: What population is most relevant, and accessible, for exploring my research problem?
• Consider how you could reach this target population to gather data. What are some challenges you might encounter?
• Determine a data collection approach for your target population. Develop an informed rationale for selecting that approach.

By Day 3

Post a cohesive response that addresses the following questions:

• What are the researchable populations in your area of practice? Which would be most appropriate for use in your research study?
• What are the challenges of obtaining a sample from this population? How could you address those challenges?
• What approach would you use to collect data from the sample? Provide a rationale for the approach you choose based on this week’s Learning Resources.

Read a selection of your colleague’s postings.

By Day 6

Respond to two of your colleagues in one of the following ways:

• Provide additional strategies for addressing challenges to obtaining a sample from the identified population
• Suggest a different population that may be appropriate for addressing the research problem
• Summarize the strengths of the data collection method identified in the post
• Share any problems or concerns over the identified data collection method
• Suggest an alternative data collection method and provide your rationale

Return to this Discussion in a few days to read the responses to your initial posting. Note what you learned and/or any insights you gained as a result of the comments made by your colleagues.

Be sure to support your work with specific citations from this week’s Learning Resources and any additional sources.

Post your responses to the Discussion based on the course requirements.>

Your Discussion postings should be written in standard edited English and follow APA guidelines as closely as possible given the constraints of the online platform.
