Nursing Research Critique and Evidenced Based Practice Plan Paper

There are two types of data collection when it comes to research studies. While they both provide an analysis of data, where they diverge is in the way that the data is collected. Quantitative data is usually numerical or measurable in some form, whereas qualitative data is based on non-numerical data. Qualitative research could involve interviews, focus groups, documents, personal accounts or papers, cultural records, or observation. Quantitative Research usually includes experiments, questionnaires, surveys, and database reports.

One of the factors distinguishing qualitative from quantitative studies is the nature of the intended outcome. Qualitative researchers seek to learn from details of the testimonies of those they are studying, also called their informants. In contrast, quantitative data are analyzed numerically to develop a statistical picture of a trend or connection (GCU, 2021). Quantitative Data is easy to collect and interpret, a cut and dry type of answer. Qualitative data is subjective and there is no one reality, but rather exists only in reference to the observer.

There are both pros and cons to each method of research. The time it takes to collect qualitative data is usually lengthy, takes place in a natural setting where social behavior can be observed, and requires expert knowledge and involvement by the researcher on the subject and must be done with care. This makes it more complex and costly which is typically why they don’t draw on a large scale of people for this type of research. However, because of close researcher involvement, the researcher gains an insider’s view of the field. This allows the researcher to find issues that are often missed (such as subtleties and complexities) by the scientific, more positivistic inquiries. (Mcleod, 2019). Quantitative data is less in-depth but contains information across a large number of cases.

As there are differences in the method of collection, so too are the general purposes for using one over the other. For example, qualitative data is more often used to gain better insight, understanding of phenomena, or be descriptive. Qualitative inquiry is often used for exploratory questions, such as “How?” or “Why?” questions.

In contrast, quantitative data is better suited when looking for evidence to establish a relationship of correlation or causation. Quantitative research aims to be more conclusive and pertain to larger populations, answering questions such as “What?”, “When?,” and “Where?”

In order to adequately answer the aforementioned questions of “What, how, when, where, and why,”, scientists and researchers must begin a formal process that includes observation, followed by a hypothesis. A hypothesis is a description of a pattern in nature or an explanation about some real-world phenomenon that can be tested through observation and experimentation. The most common way a hypothesis is used in scientific research is as a tentative, testable, and falsifiable statement that explains some observed phenomenon in nature

A good hypothesis narrows down the variables being studied, and can isolate and test the proposed potential relationship between the two. A rudimentary way of organizing a hypothesis is using the “If-and-then” type of format; where “If” briefly describes the setting, “then” is the application of an outside variable, and the “then” is a conclusion of the expected results.

In order to test the hypothesis, the researcher would need to conduct a study. Depending on what hypothesis the researcher is trying to investigate, they must consider what type of research method needs to be conducted. Qualitative and quantitative research are the most common approaches to gathering data. While both methods try to answer a hypothesis in some way, each method’s goal is different. The goal of using qualitative research is to describe a narrative about human behavior using descriptive data. However, the goal of using quantitative research is to find evidence of relationships between two or more subjects using primarily numerical data. An example of using qualitative research would be “…exploring the participant’s preference of coffee over tea, and feelings or mood one experiences after drinking this favorite hot beverage” (Rutberg & Bouikidis, 2018). This research question’s goal is to provide a narrative about a certain population of people’s preference and mood of a drink. An example of using quantitative research would be examining heart rate after drinking a caffeinated beverage (Rutberg & Bouikidis, 2018). This is different from a qualitative study because the goal is to look for relationships from two variables using numerical data (the patient’s bpm as the dependent variable).

Though a scientific hypothesis in a variety of ways, most hypotheses are either “If, then” statements or, alternatively forms of the null hypothesis. The null hypothesis sometimes is called the “no difference” hypothesis. The null hypothesis is good for experimentation because it is simple to disprove. If you disprove a null hypothesis. that is evidence for a relationship between the variables you are examining. The relationships between the two variables can be described by qualitative and quantitative results, however, with respect to scientific research and evidence based practice, it is the numerical quantitative data the forms the statistical information used to make inferences, relationships, correlation and causation.
