Understanding of evidence based practice is key for making clinical decisions. Every day clinicians use pain scales and depression scales. Quantitative research brings understanding to topics such as: primary care outcomes of nurse practitioners, modifiable health risks effect on health care costs, pain management, blood pressure monitoring. Quantitative research is made up of different types of research. Descriptive research is used to describe concepts, identify relationships among variables, or compare and contrast groups. Correlational research examines the strength of relationships among variables. Quasi-experimental studies determine the effect of an independent variable (treatment) on designated dependent variables (outcomes). Experimental studies are done in controlled settings to determine the effect of an independent variable on a dependent variable (Gray, Grove, & Sutherland, 2017). …show more content…
The researcher must set a clear hypothesis, showing the relationship between independent and dependent variables. In quantitative research tools are used to collect numerical data. The information can be gathered using questionnaires or some type of equipment. Quantitative data is efficient at testing a hypothesis, but can miss contextual detail. In quantitative research, the researcher is often objectively separated from the subject matter. One of the ways quantitative research is different from qualitative research is that quantitative research requires extraction of large amounts of statistical data. Qualitative research is focused in on personal viewpoints and opinions of a smaller number of subjects (typically). Qualitative research can take more time than quantitative research (McCusker & Gunaydin,
Qualitative research is flexible written form their results are ongoing and their conclusion can be changed while quantitative research is numerical, reliable, specific, data are collected by statistical analysis due to which quantitative are more accurate. Qualitative research uses open questions to find the depth of the information while quantitative research uses closed question, secondary data or experiments due to this it lacks the depth of the information and neglect the effect of the individuals which could be service provider, service users or other staff members.
According to Yin (2003), there are two types of research approach. This includes quantitative research approach and qualitative research approach. A quantitative research emphasizes on transforming the data to numbers, quantities and statistics to formulate facts and to uncover patterns in a research. It addresses research purposes through empirical analysis that involve numerical measurement, the relationship between variables and analysis approaches (Zikmund et al., 2010). The sample size being investigated is typically large (Anderson, 2006). Quantitative research mainly uses questionnaires, surveys and other equipment to collect numerical or measurable data (Anderson, 2006). On the other hand, a qualitative research typically emphasizes words more than numbers
What is the point in measuring something that is unique to every individual? In “The Pain Scale,” the author, Eula Biss, attempts to convey her pain to the reader. She tells the reader how she has tried to describe and measure her pain. There is a system set up for doing so, but it leaves much up to individual interpretation. The arbitrary process by which we are supposed to evaluate the level of pain we are experiencing doesn’t seem to accomplish much. Throughout the essay, Biss uses unique ways of comparing the suggested levels of pain to other “scales.” This raises the question, why can the scale, itself, doesn’t do adequate job of helping people understand pain.
Qualitative research data is useful to explain to others the outcome of the information whereas quantitative research is difficult to understand at an initial glance. An advantage to quantitative data is that it is easy for you to turn in to quantitative data, which is more aesthetically pleasing for the audience.
Methods used in psychological research are used to obtain quantitative or qualitative data. Quantitative data is more often than not derived from methods such as experiments and statistics analysing data using surveys, questionnaires and interviews. Qualitative data tends not to be aimed at finding exact measurements in its findings, but is more concerned with evidence collection and analysis through practices such as observation and ethnography (using observations through involvement in activities over a period of time) (Brownlow 2011).
In healthcare, evidence based practice (EBP) has grown and become important in providing the best quality care possible to patients. There are numerous ways to collect and use the research in the nursing profession. Studies are constantly being done to help better nursing and all of the healthcare field in order to help patients live better and maintain their health. There are different types of research such as qualitative and quantitative. Qualitative uses the human experience or something that has been lived by someone and quantitative examines for meaning and goes more in depth to research things and strives to test a hypothesis or makes use of statistical data to answer research questions (LoBiondo-Wood
It is common for researchers to compare qualitative and quantitative research methods. Quantitative methods originate from positivist and post- positivist research paradigms. Also, the methods objectively examine statistical data to determine cause and affect and often use generalizable data. There are various methods used in quantitative research such as surveys,
Quantitative research methods are objective as it uses measurements and analysis of statistical data to answer the study question. The researchers’ opinions do not affect the outcome of the study, ensuring that the study is unbiased. Another advantage is quantitative research uses numbers and statistics which is understood universally (Houser,2008).
Being in pain can make you feel unwell and have negative feelings. It can interfere with your daily activities, such as work, school, hobbies, or relationships. Pain can be a sign you have a condition that needs to be treated. A pain scale can help you describe your pain so your health care provider has a better idea of what you are feeling and how to treat your condition.
A qualitative study addresses the complexity of human experience, focusing on the big picture (Rebar & Gersch, 2015); while a quantitative study breaks a problem down into small pieces and focuses on specific parts to see how they all relate (Rebar & Gersch, 2015). Qualitative methods focus on subjective information, and never try to predict or control the phenomenon of interest (Rebar & Gersch, 2015); on the other hand, quantitative methods focus on statistics and objective information, and can yield predictions and control (Rebar & Gersch, 2015).
General speaking, quantitative research is thought to be objective, however qualitative research often involves a subjective element. There are differences designs in qualitative research in comparison to quantitative research. Qualitative research involves words, pictures, or objects; Quantitative involves data in the form of numbers and statistics.
Quantitative research involves collecting data, which can be expressed numerically. The design is well structured with pre-determined outcomes. It frequently involves testing a hypothesis, which then can be analysed from the data deductively using statistical methods. Using numerical data is easier to analysis mathematical, so larger sample sizes can be utilised compared to qualitative research, therefore giving a better representative of the population; along with simplifying the process of making a generalisation. Another advantage is that studies can easily compare to similar findings (Kruger, 2003). The disadvantages are the results are limited and might not provide a proper understanding of the topic. Also, statistics and leading questions can be used to give a false representation of the data when summarising.
To conduct quantitative research, the first step is defining the problem, identifying the objectives and goals, and establishing research questions or hypothesis. It is followed by data collection and analysis with the application of various numerical and statistical approaches. Quantitative research is more factual in terms that we get concrete data with evidence to prove the results of our research.
Quantitative studies are primarily numbers based. They deal with large cohort groups as well as analyze large amounts of data. “A quantitative
