Topic 5 DQ1 The theoretical foundations of qualitative and quantitative methods are very different, but many researchers believe both methods should be used in the research study to increase validity and reliability. What advantages or disadvantages do you see in using both types of methods in a nursing study? Support your answer with current evidence-based literature. Quantitative data includes close-ended information such as that found to measure attitudes (e.g., rating scales), behaviors (e.g., observation checklists), and performance instruments. The analysis of this type of data consists of statistically analyzing scores collected on instruments (e.g., questionnaires) or checklists to answer research questions or to test hypotheses. Qualitative data consists of open-ended information that the researcher usually gathers through interviews, focus groups and observations. The analysis of the qualitative data (words, text or behaviors) typically follows the path of aggregating it into categories of information and presenting the diversity of ideas gathered during data collection. Mixed method research has some advantages, namely: Provides strengths that offset the weaknesses of both quantitative and qualitative research. For instance, quantitative research is weak in understanding the context or setting in which people behave, something that qualitative research makes up for. On the other hand, qualitative research is seen as deficient because of the potential for biased interpretations made by the researcher and the difficulty in generalizing findings to a large group. Quantitative research does not have these weaknesses. Thus, by using both types of research, the strengths of each approach can make up for the weaknesses of the other.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
