Week 3: Research Problems, Designs, and Sample

This week, we will discuss the research design and sample for your nursing clinical issue. The research design flows from the research question and outlines the plan for the study that will answer the research question. The design identifies the major components of the study. It is important to remember that there is no one best design for a research study.

  1. After you review the designs, describe which research design you would expect to find when searching for evidence relevant to your own research question from Week 2. Why? Explain your answer.
  2. The most common sampling method is the convenience sample; therefore, many of the studies that you find for evidence use this sampling method. What are the implications for using a convenience sample on the way you interpret and use the findings?


The research question drives the research design. There is no one best research design, it is important to determine the design based on your plan for the study. Compare qualitative and quantitative research designs and outline when one would be more appropriate than the other. Let me give you an example from my practice, I facilitated large scale, oncology trials, measuring one cancer treatment against another, these needed a quantitative design because we collected large quantities of data to analyze and determine which treatment was more effective. On occasion, we also wanted to see what the patient’s experience was during their treatment, these studies involved much smaller sample sizes and we wanted to know the quality of the experience, so we collected qualitative data, in the form of interviews.

Now, reflect on your chosen nursing clinical issue. Summarize why you think one research design will work best for your research question.

You may begin posting in this week’s TDs on Sunday, July 16, 2017 for credit.

I am looking forward to our discussion.
